you are right, it wont work to make any rules about who has which rights for any domain. but i think just making it illegal to make a business about reselling domains (which includes the squatting just for selling them later), the domain market would be much better to a find a real domain matching your business case. i think companies their business case is just to buy and resell domains for higher value, do not give any value to the domain market and just make it worse.
