Yeah, that would make sense.

It should prevent both enemy invasions and spawning of enemy units imo, without it preventing destruction of blocks by players with negative alignment. A banner protection with a special banner setting for the concerning faction might do. But that should be effective without any alignment prerequisite. Some towns will require quite a few of such banners and major downside of the protection banner mechanic will be that players will go for the loot and destroy it all. Therefore, a better alternative may be to add this functionality to NPC respawners.

My thoughts also go out to these two related suggestions:

[Endorsed Clocktower Bell]

[Endorsed Defensive raids]
