It is arguable that there is still a place for investment (by that I mean, capital outlay in hopes of more capital in return over time) in a civilization and not simply storing all value in money. A prime example is in the case of needing/wanting a way to acquire more bitcoin. Bitcoin does not replicate itself into more bitcoin.

Traditionally stocks and real estate investments have been inflation hedges (perhaps not as good as bitcoin). In particular with real estate leverage via fixed income debt is method to capitalize on inflationary environments.

Taking your thinking to the extreme, every public/private company should liquidate into bitcoin and distribute it among shareholders. As you've said, owning businesses or other assets makes no sense, it is "pointless, wasteful friction"
