I don't know if it's different in the UK, but at least in the states, tech companies only have offices in the most locally-expensive areas, so if their offices were converted into co-working spaces, I'd still have to commute to them.

If every neighborhood had at least one pub and if every pub had an upstairs co-working space, that would be amazing.

edit: ah, I realize now that I took the word "shops" to mean the colloquial "tech companies", but you probably meant brick-and-mortar retail stores that have been slow-killed by the internet
