So you could've just lead with the fact that you don't care about private property and have an anti-social outlook on life. It was spelled out to you why there's value in Reddit. You say the commons are the important thing.
If I go to your living room with 3 friends and we start talking about life and philosophy, you'll ask me to leave or pay rent. But I will tell you no, you just host the place where cultural discussion is happening, I don't care if you worked hard to get your home, I'll just be there and it's not up to you to control that home forever. I could've gone into any home, the value is in my discussion, so you should be happy I'm having it there and allow me to have it for free, since there's no value in your home and you shouldn't even own it for the future.
