Please put old event housing items in Mogstation

[Xieveral]

The reason why they don't put old event furniture on the Mog Station is because it is sellable on the MB. People could buy the furniture and then sell it on the MB to make money.

Not really, if there wasn't a finite supply of event furniture the prices would plummet so there's no incentive to post it on MB. Also, they've been doing that almost immediately after the evens lately so the furnishings are trash cheap anyway. Windchimes were hoarded by those hoping to resell for big gil but there's such an abundance, you can't even give them away. Also, it may not be via MB but people do sell mogstation items,the eternal bond bands for example. Other Mogstation items that have an equivalent that can be posted on the MB are:

black/red tetsuji usagi kabuto (in-game is usagi kabuto)
metallic dyes (in-game is general purpose dye)
sweet dream attire (in-game is dream hat/tunic/boots)

So, what they could do is make a mogstation version with a different name that cannot be traded. It's not like they haven't already done this in the past, as you can see. However, I would prefer old event furniture to be made available via the calamity salvager, (though I'd be a little mad since I just blew a painful sum of gil on cherry trees for my FC house.)
