How about if you respond to what the GP actually said instead of making up things that they didn't say? It seems to me that what they actually said is that "representative democracy works better for the real people in the real world -- a large percentage of whose time, on average, is and, for maximum personal and social benefit must be, spent on non-public-policy pursuits -- than direct democracy in which every public policy question was directly submitted to the citizenry.
There may be good counterarguments against what was actually said, but the strawman you set up, and the arguments you deploy against that strawman, are not among them.
