Would you be opposed to SE implementing a program to scan for addons/parsers?

Yeah there are possible to float, but not all of them lol. You can definitely tell which houses has had the plogon treatment vs not as well, btw. Doubly so outdoors, and triple so when you find the neighbor that placed outdoor items outside their home.

Depends on how you go about it. You can legit replicate pretty much everything people do, housing-wise, without resorting to third-party tools/modifications (graphical mods notwithstanding, of course) if you're very patient. Some of it is super hard to do, though. Which I suspect is why people are so willing to take the easy route.

Players using 200 Fantasia's in less then an hour for free instantly anywhere you want and selling commissioned and non-commissioned aesthetics mods for real life money. -> No Advantages, completely playing the game as intended. Sure lets go with that.

I think we can mostly all agree the people making profit off mods exist way outside of what would typically be deemed acceptable. The Fantasia business, however, is moot; barring certain conditions (i.e. some stupid mod people use to synchronize, which most people don't use) nobody but the person changing their character's appearance is even able to see it. What's more, it's temporary - you change areas, you change gear, or really do anything that involves not standing around in a house or Limsa's aetheryte plaza, and it's gone.
