I think the challenge is that none of the blockchains has been around for more than a decade. We don't know what happens at 20, 30, or 50 years. What if, by the time we are retirement age, we don't have to cash out? What if we can live off earnings alone without powering down? It is still early in all of this. We are making a new path, which means there is nobody to show us the way.
