They do need to do something though. Why would the farmer work harder than he has to feed his own family? He can produce just enough food for himself and relax. Why would the people building houses build an extra one?
We do not live in a world with unlimited food and shelter.
Yeah I know, I wasn’t saying we do live in that world. I’m continuing to say that _wanting_ to live in that world isn’t childish. Wanting to live in a world where we are all handed food, medicine, shelter, etc. for free seems like something we should all obviously be in favor of achieving eventually. Instead, there seem to be some people who view this ideal as childish, as if even if there are enough resources for everyone, one ought to have to work to earn access to those resources, which just seems cruel and domineering.
The premise that there can be free food and housing, without people having had to work to provide them, is fantasy. Wanting to live in a fantasy is not unreasonably childish, but it is childish.
