Likewise, if he isn't really committed enough to the domain to do all that then he doesn't much need it anyway - except for sentimental reasons and/or bragging rights. Personally, if I had a domain that was of so little use to me as his, which was attracting a lot of interest, I'd just sell it to the highest bidder and be done with all the headaches.
I actually have the converse case: I have multiple domains which aren't extremely short (7 letters or more), but were bought over 10 years ago, so they're shorter than any uncommitted meaningful domains that you could buy today. Three have a lot of content and the others just have a little content. I've never been approached by anyone to buy or take any of them.
However, I did receive an offer the other day for someone to sell me one that's somewhat similar to my most valuable domain. He says he's had it for 10 years, and it's still a parked domain. There isn't any reason for me to buy it because a relatively long domain name only has value when it's associated with a website which provides useful content. Just imagine how valuable "google.com" would be if had never been anything but a parked domain. An empty 6-letter domain would be worth something at this point, but not much.
