I can really sympathize with that having been one of the people subject to those externalities, but at the same time, I have to wonder just how many such goods there are and which industries would collapse.

I'd be glad if crappy industrial jobs could be made less so, but if suddenly computers are no longer affordable to anyone due to the inability to find anyone willing to work in the myriad industrial processes that feed the semiconductor industry, I'm not sure that society will actually progress as a result and perhaps there could be less socially disruptive ways that better achieve the goals of basic income.
