Considering most farm workers are unskilled laborers making at or close to minimum wage, why would they work if they could get a UBI that covers all their needs? Farmers would still farm but that's because they own the land and directly benefit from it, they would not be able to perform all of the unskilled labor on their own. This could perhaps be offset if we drastically changed our guest worker program to allow unskilled labor in from other countries but it would have to be setup in a manner that denies these workers a UBI, otherwise they too would not work.
Same issue with building houses. The number of people wanting to perform unskilled labor would not come close to approaching the required need for unskilled laborers. For example I dont think anyone wants to be a roofer in the summer heat, the do it only for the paycheck.
Doctors? You are probably right, people will do it for the love of the work. I am very much pro UBI but there are still a ton of supporting things that need to be worked out.
They will need to raise wages above what UBI offers (which will be subsistence level to begin with, likely lower than the current minimum wage) or else offer other benefits.
If "they do it only for the paycheck" is necessary for important work, how is it different from slavery? How are we not being coerced to do things that are, at the very least, unpleasant, for the majority of our waking hours?
You wind up in a world where freedom vs slavery is a distinction without a difference.
