Your collection crashing Kodi is one of those signals your behavior is far outside the norms, nearly technically infeasible given current system .
One idea that keeps me up at night is a collection that expires itself. It’s probably like an LRU cache for music, reflecting a life-cycle that’s self-contained.
I find so much joy in hearing a song I love(d) but haven't heard in ages. Music that expires if I don't listen to it feels almost like disrespecting my past self. Sometimes my historical tastes were amazing; sometimes I'm glad I moved on; either way, I'm glad to have a record of those times and to revisit and reminisce. One can still be nostalgic about bad taste, and certainly for hits we've forgotten we've loved.
I agree with everything you said. The dream is not to compromise any of that while also expiring that which you no longer need.
There’s a passage in Infinite Jest that describes the logical point that a quantity of meat exists that I will eat over the course of my life and it could be stored in a substantially large enough room.
Similarly with our music collections, if you will, there’s only so many tunes left. The excess is what is wasteful.

I don't know if I'd quite put it that way. Maybe infeasible for one application or another (I have no experience with Kodi). But it's not hard to simply have that many files on a hard drive, in a standard Artist/Album directory structure.
Assuming 5MB per .mp3, 1.5TB is about 300K songs. No problem for a standard filesystem these days.
Maybe mirror it with another 1.5TB drive for safety, and you should be good to go for a long time.
No, it just signals that Kodi is unsuitable for the task at hand. Generalizing the capabilities of a decidedly non-mainstream application like Kodi to what is technically feasible is a bit daft.
