I mean... I'm sure it's not easy being a disabled artist but this feels a lot like undeservedly blaming the rest of society.

The benefits cliff is a real problem (and the UK seems intent on making it worse). But "ooo nasty capitalism doesn't force people to pay for art"... Come on. And disabled people have it better than at any time in history. The UK is bankrupting itself to pay for PiPs and other benefits (and pensions unfortunately).
