Plenty of musicians don't your or tour very infrequently. Tool, Godspeed, Kate Bush, and the later era Beatles are all good examples.

Maybe they weren't 'disabled' but they had their reasons for not wanting to tour.

I have my reasons for not wanting to go to work.

Economies change. Everybody has to adapt and do work that people will pay for. In music, increasingly, that means performing live.

There might be other options too. Crowdfunding new albums, maybe. Merchandising. The more we accept the new reality, the more we'll figure out.

I’d love to know of a disabled musician who fits the archetype which is typically thrown around in this discussion. It seems to be purely hypothetical.

Also, this argument discounts second order effects. Who knows what new innovations might be brought on by the need to find an alternate revenue source.

Tool also is not available on streaming sites

Tool seems like a fairly bad example because they are touring right now (not here in Australia though, sadly).

All your examples are the top of the top - most artists can't afford to not tour.

Yeah, I saw Tool twice in one year back in '16, as well as Puscifer. They're all keeping busy. Think that album's coming out this year?

They're playing new songs at concerts now, so things are looking very promising.
