If your imaginary world is all you have, is it not your real world?
That which pays thy bills is the real world.
It can correspond to another statement: that which feeds thy mouth is the real world, too.
I can't eat virtual bread. It's not the real world.
Certianly worth revolt, of course, if your first life is a horror.
But to then argue that anything other than that life is not worth struggle is a blatant denial of value of anything above bare survival.
