The main problem appears to be how it would be implemented in practice. We already did the money 'printing' part, but QE as a means of getting that money into the economy has been pretty awful (IMO and by an number of accounts), but it was relatively straightforward and cheap to do because all of the necessary mechanisms where already in place. To allocate a fixed amount of cash to every citizen, and require that debt is paid off with priority, well that's not simple at all, it requires a central database of who owns what and that doesn't exist.
