I typically suggest something like your first 25 domains are exempt, registered businesses also get some reasonable amount. Past that there should be a relatively hefty squatting fee. Maybe additional exemptions can be applied for.

Who is going to monitor this? How do you enforce this globally? What about defensive registrations? I know some companies register thousands of typos, spend millions protecting their brand. Is it on a per TLD basis? It would have to be since different TLDs have their own rules, especially ccTLDs which are governed by their own countries. How do you prevent the oversight organization from being captured by vested interests or IP lobby?

There are so many details which cause problems with these 'simple' solutions which once you start digging, you end up having to compromise a lot and end up with an equally, if not more, shitty solution.
