I don't think HN has a monopoly on discussion between people with (slightly) above-average critical thinking skills. Many sub-reddits fit that definition as well. I don't follow how this would be impossible to enforce. The person whose content on youtube is removed for example is going to complain. It's dead simple to slap youtube with a couple million dollar fine for such things.
