Not all money that government generates comes from tax payers.

From selling stamps, casino taxes, parking/speeding tickets, lotteries (where out of state purchases are allowed) to charging fees for applications or rent/selling land or charging fees to camp in parks.

I don't have to be a taxpayer for the government to make money from me.

Thinking the govermment is the taxpayer is wrong. The government must represent all citizens very young and old and many are not taxpayers.
