Point that people may get lazy is most deeply already debunked as each and every test has proven other wice.

Prices will go up just doesn't make any sense. People get much more active, which in turn increases competition and self employment, making achieving of market dominance much harder. Problem with many of those points in that text is that it is just speculation without much of a proof it self. I'm also getting very tired of debunking some of these claims as I live in finland were all the socialists and their unions are talking all that non-sense. I have seen few good articles here on steemit about proof of work for basic-income but I don't have energy to dig them up. Sorry for this half-assed answer.
