“If Bitcoin succeeds, why is for profit capitalism the automatic winner IF it is still just a theory? Why couldn’t other systems like profit sharing, co-op, or even fully socialized industries survive perfectly fine and better than for profit capitalism?”

Because those models likely rely on a centralized authority, which definitionally suppresses the free market and is therefore likely to be outcompeted by the free market in the long run.

Sure, I could see a few small pockets of profit sharing, co-op, or full socialism on the bitcoin standard consisting of those who voluntarily choose those models.

But the desire to contribute and create value is a key component of the human condition. Most humans want to create a better future for their offspring than the present. So I’d expect the global free market to dominate, while other models survive as small boats lifted by the rising tide of the global free market on sound money.
