1. Collective action makes progress a lot easier
2. Democracy is the least worst way to do it
3. I'm fine with violence not being a free market value
I think you'll find that the large majority of people agree with the third point, and even without democracy, the will of the large majority will impose itself onto everyone except in very few cases.
As I said in other threads, existence of things does not justify itself.
The fact that majority of people can force anyone in minority to comply does not say anything about morality.
I point out that people tell themselves that it is okay if majority seemingly "decide" to to allow someone to kill some people. I question that belief which oddly looks very similar to any religious dogma.
You advocate for "progress" and "democracy is the lest worst". I'm fine with it, live your life and participate in democracy. But let me politely disagree with you. Will you not participate in "majority" that tries to kill me if I don't give them my stuff?
