In our civilized societies we are rich. Why then are the many poor? Why this painful drudgery for the masses? Why, even to the best-paid workman, this uncertainty for the morrow, in the midst of all the wealth inherited from the past, and in spite of the powerful means of production, which could ensure comfort to all, in return for a few hours daily toil? - Peter Kropotkin (1892)
You wouldn’t be happy as fuck for long. Eventually you’d get bored enough that you’d start doing something. Doing something is work.
That’s kind of the point though, when left go their own devices people generally choose to work, its just that when their base needs are met they will tend to work that brings them joy first instead of pay.
Yeah I’d most likely engage more with my hobbies, but nobody is paying me to go on walks or write some awful reviews of movies and videogames. They instead pay me to pump air into cow carcaases for 8.5 hours in a 30-35 degree room. Something that leaves me exhausted and basically no time to do things that make me not want to blow my brains out unless my epileptic ass wants to start depriving myself of sleep.
