Needed: History is incomplete.
Velma sometimes helps give tours. She has no enthusiasm about it because she knows all the ghosts are fake.
When Mystery Inc. destroyed the Evil Entity, the universe was altered, creating a town that was unaffected by its influence and thus having no need to make a museum for all the strange phenomena and fake monsters terrorizing Crystal Cove.

Scooby-Doo! Mystery Incorporated
Velma led a tour group there, and ended getting shushed by her parents for being too honest about the fake ghosts.
Fred Jones and Daphne Blake visited the museum after-hours as a date. They mentioned that Flim-Flam was in jail for con artistry, and that in regards to Scrappy-Doo, Fred swore that they would never to speak of him again.
The gang went there to get information about aliens.
Insert details here. (Gates of Gloom)
When the Evil Entity was destroyed, it altered reality for all of Crystal Cove; meaning there was nothing to make profit from. There was no sign above the front door, implying it was just a regular shop.
