Seller determines the price.
It is not a counter argument, it is a fact
Seller set price (and can freely change it at will). Buyer agree or disagree. They BOTH make a deal, or not, by agreement, or disagreement on price, set by the seller. It's all up to the seller.
More generally speaking.. If sellers decides they really don't want to sell then supply goes down. Values of domains goes up, but number of sales goes down. Btw seller/nations etc. does this to drive prices up (like oil prices)
Obviously, if "the market" determines (and I agree with you), market isn't only buyers, but sellers also. The all/both contribute. Therefor it's true when people say sellers determines, and it's also true when people say buyers determines.
That's how I see it.
me too !
