I'm with the good doctor. This is using an unnecessarily powerful tool (half the reason amnesia is so widely disliked is because it is so powerful!) for a goal that...I don't really think even needs to be achieved?
If they're this hostile to outsiders, just have the party be shooed away by the residents until it's time to go there "for real." That preserves the mystery without taking away any agency; it's not like the characters have always been able to go to every single place they ever wished to go. (Otherwise, I'm sure some enterprising players would be paying a visit to the royal treasury now and then...)
I'm not totally against the use of amnesia, but in general I'd prefer that it be confined to some place or places where it's already expected that the party is "losing" some of the context they might otherwise have had. For example, having this be the inciting incident of a campaign is perfectly fine, because it's already understood that a lot of Offscreen Stuff comes into play before the campaign begins--indeed, beginning with amnesia could be a good way to let the characters develop naturally "on camera". Likewise, if there's a clear time-skip or "montage" moment, that can be a reasonable spot to have some amnesic shenanigans, because it's already understood that stuff is getting glossed over; this is doubly true if the party actually agrees to the amnesia in advance, so they know they're losing some memories.
