If you have that sort of mind, making things is ridiculous fun. Taking a few ordinary materials
and some post-industrial tools that you have bought at substantial expense
and manipulating them into a useful object is entertaining, and when you're done you have a table, or a circuit, or a dress. You can get items customized to your own tastes without having to pay a fortune... as long as you don't cost in your own labor.
The catch is that, until you've spent years practicing the necessary skills and learning which materials suppliers have quality goods, the object you produce won't be as good as the ones created by either an industrial business or a custom maker. There are decades and centuries and in some cases millennia of expertise lying dormant in any created object. Much of the time, your sloppily welded, rough-sawn, lumpy-seamed object is good enough, and you can have fun looking at it and saying "I made it!" Somebody who works in the craft/industry you're emulating will look at the same object and see a macaroni drawing hung on the refrigerator.
I first noticed this when I worked in a company full of very, very bright engineers. Far too many of them were confident, by virtue of that brightness, that they could do anybody else's job. They knew more about kitchen logistics, or ingredient buying, or repairing sprinklers, or cleaning than the professionals -- because of the mathematical or mechanical (mostly) intelligence that had gotten them through the top schools. The truth is that anybody else's job looks easy until you watch them do it. I am always astonished when (with permission) I sit on the floor and watch what the electrician, the plumber, the carpenter are doing to my house. You need to know a lot of stuff about how a house is made to walk into any particular house and sort out its mechanical systems. Plumbing is like surgery -- knowing where the pipes are in a platonic object isn't the same as having your hands deep in the guts of a particular object.
Take me. I've been sewing for over forty years, off and on. Note the "off and on". I sew when I feel like it, when I have the spare time, when I'm not doing the job in which I have professional expertise. When I go to a class with serious costumers, I am always, always the last person to finish any step in the process. My finished garment or object is clumsier than those produced by the everyday seamstresses (sters), because I don't have the hundreds or thousands of hours of practice that they do. Their objects, in turn, seldom approach the highest standards reached by people hundreds of years ago who did nothing but hand-sew all day, every day. Very, very few can handspin a thread fine enough to match the Shetland or Orenburg spinners. Indeed, not that many can handspin a thread fine enough to weave. You cannot get linen approaching the finest quality produced in the 1600s, either handmade or machine-made. People who work in living history museums, when interviewed, always marvel at the skills they are imitating.
Another example of this is backyard farming. Animal shelters are starting to have a problem with abandoned urban chickens
(note useful debunking). Why? Because eggs can contain either hens or roosters, and roosters are useful only as food. Straight-run hatchery chicks are less expensive than sexed chickens*, and backyard chicks have no guarantees at all. Finally, the maximum lifespan of a layer is years longer than the useful egg-producing period. Farmers solve this problem by killing unwanted chickens for the stewpot (historic) or fertilizer (modern). Many -- not all -- backyard farmers don't want to slaughter birds themselves, so off to the shelter they go. (I am very, very skeptical of the article's using Marin shelters to minimize this; Marin is its own little planet.)
Anybody keeping backyard goats quickly discovers that male goats are nasty creatures that not only stink but can cause your does' milk to be inedible. Again, the historical answer is roast kid or goat curry. This takes goatkeeping from the pleasantly pastoral to the ineluctably bloody. Free-range backyard eggs taste fabulous, but the downside is fighting predators that can't get into a closed battery house. I haven't even touched on the thousands of nasty diseases chickens, goats, and pigs are not so much heir to as enthusiastic boarding-houses for. Animal husbandry is a matter of both skill and luck, and no matter what scale you practice it on, there's a lot of unexpected death.
I love heirloom tomatoes. The hybrids don't, in general -- Early Girl is fabulous -- have as deep a flavor as the open-pollinated plants. Propaganda notwithstanding, the heirlooms in my garden are much more disease-prone than the VFNT** F1 hybrids.
Crafts are awesome. Making things is awesome. Growing things is awesome. But if creating something at home makes you undervalue the expertise and skill of people who do it on a commercial scale, you're doing it wrong.
* Yes, chicken sexing is a real skill, and an esoteric one. You try looking at a new-hatched chick's ass and figuring out which kind of cloaca it has.
** Huh. It isn't VFNT, any more; the toughest hybrids are now VFFNTA, which means resistant to verticillium wilt, fusarium wilt, nematodes, tobacco mosaic virus, and alternaria leaf spot. How many beginning gardeners know to look for those letters?
