But none of us decide what our cage looks like, now. Our cage now is capitalism, wage labor, disease, death, suffering. We already are tossing the environment in the meat grinder, and many people already have very limited freedom of movement due to poverty, government choices, or circumstance.

You can argue that, at least for democratic countries, these are choices we've made of our own self-determination, but is that even fair to the millions or billions who have far less self-determination?

The cage imposed by nature or by the leaders of whatever country you're born in is just not a very good cage for a lot of people.

Then we should strive to give more people a chance at greater self-determination, not the opposite.
