'Have' to? Who decides that?
society, the economic system? why do you have to work now?
You don't
lol, most people have to (unless they have some generational pre-built wealth)
today’s society literally requires that you work. you can’t get land to “grow your own food or farm” unless you buy it. To buy land, you need money (a construct created by the government) and the only way to gain money/wealth is by working
That is dramatically incorrect. There is not a single person that has to do anything.
how would they survive if they didn’t work then?
yeah, but then the government will imprison you (take away your freedom, prosecute you/decide how it wishes to enact justice). You can’t escape being responsible to society at this point. All land has been claimed in the world
