If you extend this into making/mending your own clothing, doing your own plumbing, electricity etc., suddenly all your time goes to these "maintenance" tasks.

If you extend this into making/mending your own clothing, doing your own plumbing, electricity etc., suddenly all your time goes to these "maintenance" tasks. Sure if you're growing food as well on the side so that you can sustain yourself completely, it could be a happy way of living life. But if you have to work 8 hours per day to make a living, the spare time is valuable and subject to prioritization. Some people do some of these things on the side, as a pleasant hobby, but practically no "modern person" does all of them.
