Why even "apologize" like that? You don't have to.
For some reason people seem to think that there could be a cost effective way to truly determine what the best use of each and every domain name is and allocate it to the truly deserving users!.
And that if that was even done then a user with more money wouldn't then come along later and buy it from that person by paying them money.
You know I remember way back in 2001 - I think it was. And I would have attorney's contact me wanting to know if they could use law.com for their website. You know as if they just woke up one morning, had this idea, and nobody else thought of using law.com for the same purpose. They were the first! That's how little they knew about the internet prior to that thought.
Likewise, many startups seem frustrated that the name that they want is being held for ransom by some other person. As if nobody else would have come along and used it for their business and they wouldn't be able to use it.
And regarding the public resource, it really is a public resource. You may have to go through a registrar, but it is open for any and all to register. In the case of "squatters", it is the same as attempting to rent a parking space. Something meant for the public to use which requires a nominal fee.
Also, I'm not sure what you mean with 'public resource' in this context, domains are more like private registries held by semi-official companies that you can choose to do business with or not.
There is a near infinity of them, shorter ones are obviously in short supply but to date I've never ever had a problem buying a domain for a new project for $8 or so.
