It strikes me as awfully out of touch because that's exactly what we've been doing all along, yet we don't see the results we want. So either it's our fault because we just suck at this voting thing, or there are systemic inefficiencies in our elective representative democracy.
Liquid democracy seems to be the ideal form of democracy because it gives every citizen the freedom to vote directly on the issues, or to delegate their vote if they wish. Liquid democracy was not technically feasible in 1787 when the U.S. Constitution was written, but technology has come a long way since then.
It's a shame that it's almost considered sacrilege to even suggest that the political system our founding fathers devised over 200 years ago may not actually be perfect in 2020, and could be improved with some modernization.
