Some housing items should be available easier

[Xelanar]

It is entirely an incentive to do otherwise unpopular content from the game. It's not unique to retainers either, Eureka has unique furniture, old savages have unique furniture. Like you I'm annoyed the system works this way, but if it didn't then who's to say that part of content wouldn't die? A lot of people I know don't bother with ventures and just use retainers for storage, but having items locked behind leveling it encourages players to use them to their full extent and rewards them for doing so.

I am perfectly fine with housing items being gated behind content like retainer ventures, submarines, Eureka or Alexander. You missed my point though.
I am calling out items being badly accessible that you require in bulk to do things. Meaning multiples. Lots of.

How am I supposed to build a room with Stone Partitions, if a single partition is only accessible through 18 hour ventures IF I get lucky? To make a single room I need say... 10 of those? Probably more, depending on size, but you get the idea.
The same goes for Neon Wall Lights. There is no way a single one is enough. Even to illuminate an apartment or a small house I would still need many.

These items are so inaccessible, that I cannot use them anywhere because of the amount required.

Hence I'm pleading to restrict incentivising items to vanity things like plushies or weapon stands, if the content they insentivise cannot be reasonably farmed.
