That's sorta where I'm coming from.
1) There really are no shortage of good recordings of good performances of any Chopin composition. Makes investing sight unseen somewhat questionable. It's unclear that a mediocre human performance is actually a lot better than nothing.
2) There is no particular reason to believe that recordings of Chopin pieces are going to become hard to find, or overpriced, in the future. There's no shortage of interest, and no shortage of sheet music. Heck, I'm seeing a huge resurgence of interest in classical and "early" music.
3) If your concern is that the music industry is becoming overly focused on pop and other high-profit areas... the way to fix that would seem to be to start a publishing house, not a recording house. Or to simply support the publishing houses which already paint a wide swath into the less-charted areas, and to enter into a dialog with them if you think there's something they're missing.
I don't feel a need to support it based on the arguments they've advanced. There are better places, and reasons, to invest.
