Multisig does not nullify $5 wrench attack defense.
First off, multisig is long term savings, deposit only. Ideally, you don't even have that wallet anywhere on you. If you want to keep a smaller amount of bitcoin accessible to spend from, you can totally do that.
Second, if for whatever reason, you want to keep a multisig HWW on you, you can still use something like cold card that has duress defense options.
But IMO, a multisig wallet is a GREAT decoy wallet. You can just hand it over, give them the PIN and everything.
