Important #DnD question: would a permanent teleportation circle still work if you just... put a big rug on it?

Some DM: teleportation sigils are closely guarded secrets. Most people can& #39;t use them to fast travel between cities because if they saw them, they could recreate it and teleport an army in or something

Me: 2 big rugs

Someone: you can only teleport to one location. If you wanted to make your own circle you& #39;d have to stay in the same place for a year

Me, every day in game: I cast teleportation circle on the rug again

The fact that teleportation exists but isn& #39;t used for mass transit of goods and people in most (any?) settings, and is instead just used for political/religious leaders and the occasional party of assholes is a travesty tbh

I see 3 possibilities re: rug on a circle:
1. It stops working (cool, locked the door I guess)
2. It keeps working and someone who teleports to it appears under the rug (objectively funny)
3. It keeps working and anyone who walks on the rug gets teleported, possibly by accident
