What exactly makes someone entitled to a domain name more than me if it isn't an already established brand/trademark? If the argument is "you're not using it" - Maybe so, but maybe I might want to use it in the future, maybe an associate of mine could use it in the future, maybe I might even want to pass it down to family, but regardless of the fact, it is my possession.
Can I take food off of someone's plate in a restaurant and say "well, you're not eating it."
Would I be taken seriously if I gave the owner of a house a lowball offer with the argument "you don't live in it, I would!"
What I think the problem is: our industry is so big in regards to the amount of domains acquired and listed for sale, yet so small in regards to public knowledge of aftermarkets that people can't wrap their head around their value because they've never seen them marketed in this way.
If GoDaddy were to advertise their auction platform on the main page with "Buy A Premium Domain!" or one of the other aftermarkets ran a TV campaign for purchasing Premium domains, it would be a step moving forward to public awareness and aftermarket sales would go up.
Notice how tech, internet-related, adult-related industries pay good (fair) money for a Premium domain, is it because they have more money? No, I think it's because they understand domains more than any other type of business, they understand online branding.
Once/if domain investing and domain aftermarkets become more mainstream (which I think it will overtime) I think the term "cybersquatter" will become obsolete.
Domaining could be a pastime or a sleeping giant, time will tell.
