The price is fine where its at. Its one of the very few things that ArenaNet has adjusted for inflation.
Also know that MANY players around you own a tag but don’t always throw it up (thankfully).
You’re welcome. 
Seriously though, as many times as I’ve wished that between 5 and 20 commanders would turn off their tags so I can see map markers, I cannot agree that it needs to be any less expensive than it is. I would hate myself if I actually called for it to be more expensive though, so I’ll say I think the price is in a good place.
