I actually want to adjust my response. I think the question of whether or not technology CAN fix anything is always a loaded question.

Yes, it CAN fix this. However, within the context of the nostr protocol, it is not really feasible. It would take distributed storage and hosting solutions to fix such a problem, not a communication protocol. So perhaps at the relay level it could be done, but from outside the scope of the project.

However, Bitcoin could fix this. A recent example of Bitcoin doing just this is gputopia using lightning payments to facilitate buying and selling of distributed GPU compute power. Distributing storage would come with it's own challenges, but could be solved with Bitcoin very similarly.
