Garage/yard sales are fucking based. Why? Because they are one of if not the most libertarian forms of association we have in our current statist society, especially if you don't put them on your taxes which I bet most people do anyway.
We should embrace yard sales more. Stop donating shit to Goodwill. It's time that you get something out of your unwanted shit. Sell more then just your used shit. Sell your crafts, produce, 3D printed items, etc. We could probably have a full blown ancap/agorist revolution if we start embracing yard sales.
