Why not?
If you want to buy something, you first need to understand the market and get at least a range of recent prices paid for similar examples. Otherwise you're a drooling idiot.
If I asked you the going rate for a 460-acre farm in Southwestern Saskatchewan with 6 small 1700 square foot employee lodgings, a medium 3200 square foot guest house, and a large 5000 square foot ranch house on it, 7 barns, 3 large silos, a 16-car garage, and a 48-horse stable... you'd just give me the current, average going price, right?
Right off the top of your head, huh? Since you know the exact prices as of May 21, 2024 for every property in the world?
Obviously not, and first you'd have a to do a lot of research and hire a few real estate brokers to run the numbers before you even had an idea on how much to offer.
Same thing here and to excuse these hobos offering $3K for a premium domain is no different than someone offering $3K for a Picasso or $3K for a used Bentley or $3K for copy of Actions Comics 1 or $3K for a prime piece of real estate.
Idiots.
