All in all, drawing comparisons between something like a domain and real world objects are disingenuous at best. I'm not going to detail how apple.com is different from your Ford Pinto.
You do not own a domain. That is false right off the bat. And no, you cannot do with it as you please. For example, buying a trademarked name and then trying to extort money out of the owner of said trademark is not allowed.
If you are renting a domain with the sole intent to deprive someone else the ability to use it unless they pay an extortionist fee, that is wrong. It goes against the free spirit that the internet was built on. The fee charged is at least in part to prevent a massive "land grab" of domains that are to be sold off at absurd prices.
