The spell teleportation circle lets you teleport between a chalk circle you create to a permanent circle you are aware of. Creating the chalk circle costs 50 gp. This is high from a commoner perspective, but affordable for the 9th level wizards that will be teleporting.
However, creating a permanent circle requires "you" to cast the spell in the same location every day for one year. Which means consuming 50 gp of gem encrusted chalk each and every single day for 365 days. That's 18,250 gold pieces! Miss a day? Start again. Get sick or want to adventure? Start again. Region runs out of sapphire chalk? Start again.
While a single good treasure hoard (level 11 to 16) might hold enough gold, that's a lot to ask a single character to pay (and said treasure hoard would be split between the party, so it's everyone's treasure).
But what kingdom would fork over that money for a circle? That's a tonne of cash - a literal dragon hoard - for something only rare wizards can use.
And they'd have to pay the wage for the wizard to cast said spell again and again. That could conceivably radically increase the price. (Even in a 3e Eberron campaign, where wizards were common and spellcasting costs codified, a single casting would have a cost of 450 gp.)
Keep in mind that the spell is literally useless without permanent teleportation circles, and the circles are useless without a mid-level wizard.
They don't even make much sense from a worldbuilding perspective. You'd never put one in a castle, since that's a giant security hole for invasions. Using one for trade seems unlikely given the sizable initial investment and the need to burn at least 50 gp each time you open the portal (50 gp being 500 lbs of wheat, 25 sheep, or 5 cows). For the price of creating a single portal you could charter a fleet of five ships to sail 100 miles away.
Just something that leapt out at me in the rules.
