Had they been forced to, that would simply be slavery.

Having a mutual obligation to care for others in your community is exactly the same as being rounded up at gunpoint, ripped from your homeland, shipped to a field or a mine halfway across the world, and forced to toil all day every day for barely enough to survive on until you inevitably succumb to the horrible conditions inflicted upon you

It is difficult for me to imagine what "personal liberty" is enjoyed by an unemployed person, who goes about hungry, and cannot find employment. Real liberty can exist only where exploitation has been abolished, where there is no oppression of some by others, where there is no unemployment and poverty, where a man is not haunted by the fear of being tomorrow deprived of work, of home and of bread. Only in such a society is real, and not paper, personal and every other liberty possible.
