Actually you made a statement, one insinuating I don't contribute to society, THEN you asked a question...

I can not speak for your country, I can only speak for my own. Conversely systems of taxation are usually similar world wide, and I imagine your own system of taxation is largely focused around paying interest on money printed out of thin air.

To your point, you ASSUME no one will pay for roads... but guess what. Private industry has plenty of incentive to do so own its own. The government does not build roads, contractors do. Furthermore to my point, the majority of taxation simply goes to banks who have the privilege of printing money for nothing, NOT infrastructure.
