Minimum prices blocks TP
There was a Dev comment on this long ago. You can use Google to try and find it, if you so desire.
Good luck.
It would be nice to have. I don’t think it’s worth the cost.
Each too-low-to-fulfill offer represents a chunk of coin that a player has left in “escrow” with the TP. The devs would have to program a script to identify such offers, delist them, and return the money to the bidder. That part isn’t so difficult or time intensive.
However, the error-preventing, testing, and troubleshooting required to ensure this goes smoothly would require a massive amount of effort. Further, given the number of transactions and the fact that most people who have such offers don’t remember, it’s inevitable that there will be some post-implementation issues. People will complain about not getting money they expected, the TP history could get confused, and I’m sure there’s more than a few people who are leaving those offers up for whatever reasons.
And the benefits are tiny. It means a small number of transactions would be a small bit easier than they are today. Right now, the worst thing that happens is you have to adjust prices slightly more often than you want or that some speculators are mislead by the price spread between lowest sell price and highest buy offer.
tl;dr it’s a lot more effort than the limited benefits would warrant, at least in my opinion.
Some history:
Originally, you could make offers at any price, regardless of vendor value. Later, due almost entirely to community feedback, ANet put in “floor” pricing, that is it preventing making offers for less than vendor value + 1 copper. Later, again due to community feedback, it was changed to vendor value + 18% (rounded up). The idea behind the paternalism was to prevent people selling for a price that would net them less than the vendor value. That is, people used to complain that folks were “losing” money.
