Your keys can be totally secure, but the State will happily ruin your life simply for appearing to defy them. The State can take your house, your car, your children via CPS, ruin your marriage (resulting in divorce), freeze all your bank accounts, take your guns, shoot your pets, have the IRS audit you and all your friends/family annually for years, and then throw you into an insane asylum for the rest of your life, because "he's a crazy Bitcoiner". The State won't suffer an iota from doing all that -- they will rather enjoy the revenge they take upon you for defying them.

They can do all that, meanwhile your BTC remains forever un-seized, never to be seen again, because all your friends and family think you're insane -- because the State told them you're insane.

All your stuff can be secure, but if you aren't secure, then all your stuff is garbage.
