I don't think your opponent believes that the US system is a "representative democracy" or a "democracy" or whatever it is that lets N-1 people take arbitrary stuff from 1 person. Your "rally support" solution would not fix the situation.
[edit] More directly to your point, it's irrelevant what anyone thinks is "letting" government "steal", the "thievery" is enabled by laws which are created by elected representatives, therefore "the people" (aka government) is directly responsible for taxation.
