A few, not a lot.

The entitlement is real.
We already have one. They're called luddites. They've always existed, and will bemoan any new technological advancement.
Not if you want gaming performance.
Leechers do not in any way improve the service, i.e. swarm. They harm the swarm by providing nothing to the swarm.
You might get that 10gb movie downloaded in a day or so...
Public torrent users are 99.9% leeches. No thanks.
Most of the private trackers I'm a member of were started by 3 or 4 people.
No, since that would be sanctioned as well.
You missed the point. We aren't "shopping" at any gas station. As a consumer, I'm going to consume, whether you wish to sell (not rent) it to me or not. Don't wish to sell? Fine. We will take it anyway.
You downloaded that torrent from seeds. If you don't seed, you're just a leech. Do you like leeches in real life?
If you're this concerned, just stick with public trackers or usenet. Private trackers have rules for a reason. If you're so paranoid about them, avoid them.
