Given that we don't even know why they were seized (or how many were seized by each person), it seems like you have an amazing hostility towards domainers in general.
Imagine a shopping mall car park where it costs $0.20 a day to park. Except you can't park anywhere near the door, because people turn up at the start of the day, park their cars across three prime spaces, and offer to sell them - for $20.
You'd have to be a big fan of the coase theorem to enjoy paying $20 for a $0.20 parking space, when the only thing the seller has done to add value is get in your way.
While this is an entertaining hypothetical, I think Coase would say that you should go & offer the shopping mall $0.50 to rent you the spot. And the price might still end up being $20.
Applicability to domains: maybe they should all be auctioned?
Or - if you simply look at it as real estate - they bought that land when the supermarket was being built (and no one else thought it was valuable).
In this space - it's akin much more to having parking spaces near a sporting event or concert. In which case - there's lot of happy people willing to pay $20 for the privilege of parking.
Also - you should know that pricing goods based on "what they cost" isn't the proper way to valuate a property, service, etc. If that was the case, every user past 1,000 in most SAAS apps should just ask for their subscription to be free.
No, the mall bought the land and made the parking spaces. They are merely squatting on parking spaces that other people created. And the reason those parking spaces were created was to enable actual, productive business to take place, not to feed parasites.
They are parasites. They add nothing to the system.
In some cases, speculators provide actual value. E.g., they prove or maintain the assets that they speculate on. In others, as with financial speculators, they provide liquidity to the market.
Neither is true for domain speculators. They get paid for making the world worse.
You're making broad assumptions on a lot of people.
Some domainners have lots of domains & develop lots of them into valuable properties. Sure - they have a few that are parked - but that's a percentage.
Typically - money is a measure of value you add to the world. They have to be adding some sort of value in the world or they wouldn't be able to extract value from their activities.
On average, money is a measure of added value. But plenty of people extract cash without creating value. Thieves, for example. Corporate raiders. Many speculators in the financial market. People running protection rackets. People running MLM schemes.
The classic medieval example is a bandit or a warlord who take over a section of road and extracts tolls. He didn't build the road, but he can extract plenty of money as long as he controls it.
All you really need to read is the language, they aren't people they're 'shady domain land grabbers'.
You can tell from the language that the OP knew of an opportunity to buy mispriced assets and/or renew their domain, and having failed to take the opportunity is now upset at others having taken the opportunities they missed.
You know the kind of people that couldn't be bothered to spend $90 for a 10 year registration and now have to pay a few hundred to get a domain back they wasn't worth $10, or clicking the 'auto-renew' button to them.
Given that you have 75 days to renew your domain after it's lapsed renewal - it's not really taking advantage of anyone.
There has to be some mechanism to release unused & unregistered domains back to the market.
And careful - you just dehumanized an entire set of people ("they're not people") because of the work they do. Domainners might be annoying - but they're not gangsters.
Because it's done with the purpose of eventually giving some one a shake down ergo eventually might have a use for the domain.
Only reason they they let this happen is because it's good for business. I'm sure domain like 95 percent of domain registrations are done by these so called "domainers" or people protecting themselves from then.
What makes you so mad towards them?
