1. If we really need consistently good piano sound quality, maybe we should replace the unreliable pianos overly susceptible to humidity and wear with computer synthesizers that can be told exactly how to sound? I mean that leaves just the speaker housing and wear on the input interface.

2. Maybe music is actually a hobby and not really necessary to be produced reliably. Maybe the fun is in the negotiation with instruments and people?

If the priority is a diverse, fun, culture, maybe don't structure all economy and politics around the idea forcing people to justify their existence.
