I didn't think I was convincing anyone to run anything, just explaining that this approach wouldn't work. Moreover, there's always a possibility that you, a “decent person” can become a “criminal” one day, and, counter-intuitively, that's when you want the laws to work and be equal for everyone, not when you're a “decent person”.
But it doesn't need to be so dramatic. Like most of the people on this site, you probably use more or less cheap broadband or mobile internet at home. The reason it's much cheaper than a dedicated line to your location is because a lot of people in your area want an internet connection, too (and they don't use it fully, or all at the same time, etc.), so there's a great deal of ISP infrastructure sharing. So you help your neighbor in having a cheap internet access, and your neighbor helps you.
What if one of your neighbors is a maniac who streams killing people, or a botnet owner, or a military drone operator working from home, or just a domestic abuser? Have you asked your provider to only join the “decent people” network? If not, you are actively helping bad people right now.
