Even if you wanted to opt out of capitalism, I can’t even think of how a poor person would manage to live legally in the US. You basically have to be a hobo constantly in fear of being arrested (and then in prison you’re definitely a slave). You can’t just go out into nature and build your own homestead like people used to do.
I can see why you think it’s similar, but it’s assuredly not the same as slavery. As a hobo, you still have rights and cannot be purchased or treated a literal property.
