I've thought about this as a commercial operation in the UK; but TBH I can't see that you could make enough money from it. However, it does seem to serve a very useful function in society, and would be something I'd want to fund through government - but it goes against commercial interests (people with repairs don't buy as much stuff).
We're getting some charities working to help people make repairs, some maker-spaces and such that facilitate people doing it themselves, etc..
