Here is were you are very wrong. As sound money is adopted it will look like the stock market is exploding. FIAT will be hyperinflation and it will settle with the usual suspects. Real Estate, equities and to a lesser extent commodities. They will learn from Saylor and come up with their own strategies for Bitcoin acquisition. The mindless masses will be throwing their FIAT into the equity casino trying to get a bitcoin multiplier before their fiat evaporates. Once FIAT is in nonsensical free fall or gone yes the market will slow because there won't be funny money for them suck off the tit of the worker.
Then there will be no zombie companies. It will go back to how the stock market was in the early days. You will pay a dividend or have an amazing pathway toward a huge dividend or there is no reason for anyone to buy a stock.
I mean really think about that. We are so late in the FIAT shit hole that it is almost a faux pas to give a dividend. It is insane.
So I agree with you in the end state after the full conversion, stocks and real estate will lose their escape from FIAT premium but during the transition stocks are going to skyrocket in a manner we could never imagine today.
