I have no problem with familiar countermeasures existing if they makes sense for your world building. Infallible countermeasures are another thing entirely, and highly suspect.It’s interesting that some of the same people who claim the wizard is OP also decry anything the NPCs might do to counter the threat of magic as DMs punishing wizards.
In a world in which magic is common, and familiars are easy to get, you would think anti-familiar measures would be common place. As common as locks in a world full of thieves. Every evil mastermind would tell their minions “and make sure to pick up a familiar-hunting terrier from Target!” Except those novice masterminds who don’t realize minions need to be told everything.
I mostly skimmed the debate upthread about castle construction, but I think @Oofta had it about right.
There is an inherent contradiction between the claim that wizards are the terror of Faerun (or wherever) and the claim that attempts to counter that threat would not be commonplace.
Thieves (rogues) exist and would be an issue for these same peole, right? So why isn't the rogue encountering perfect countermeasures when he scouts ahead? That also makes sense from a world building perspective.
If you have one but not the other, then you're probably not doing it for the sake of world building.
