Similar in flight rules: one cannot fly a paraglider over "congested area". But what is "congested area" is intentionally not defined in the rules, and left up to judges to decide for each case separately.
Because if FAA tries to come up with a definition, there will always be weird unjust corner cases. Or just ban the paragliders whatsoever. I think the current ambiguity is the best compromise.
