By that logic, Google, Amazon, WalMart, and every other government on the planet have not constructed a single one of the buildings it uses either. Nor has any organization except a self sufficient prepper or hippie commune. And even then I bet they all had to hire some contractors.

Also by that logic all taxation is theft, which sure buddy, go live out your libertarian fantasies in Somalia.

Somalia has four governments, not zero. More government, more problems.

Also, while I have plenty of grievances with Google and Amazon, neither of them (nor Walmart) has ever forced customers to give them money under implied threat of sending a SWAT team to your house at 3 AM, throwing a flashback through your window, and having a team of men armed with assault rifles abduct you and throw you in a cage for not paying them money that you never voluntarily agreed to pay them.
