I think it's a shame that people don't gather to play music together. (Or get together for much of anything else except to drink beer and scream at the TV over some sports game).
I'd like to see more mom & pop coffee shops/bistros have music nights. I imagine that unpaid musicians strutting their stuff and musical talents for the (mostly uninterested) patrons would be a good thing for the business because it would bring in more business. Or it should.
As for electronic pianos outselling traditional strings, the new stuff is lighter, smaller, and never needs tuning. They doesn't sound nearly as good, but most people haven't ever heard a concert grand in full-throated splendor so they wouldn't know.
As for venues, try the local lodges. Many of them have small spaces for membership events and might be willing to host events for outsiders for a small fee or even, hopefully, free. These are usually adult spaces so kid events might not go over with the general membership but many have youth organizations that could be approached.
