Is the fourth amendment always the right thing to follow, if you really care about privacy?

If you have any data that you’re willing to protect wholeheartedly, should you always believe in yourself to protect it?

If you have anything stored in a phone or external hard drive, computer, etc for yourself or someone else that you wish no one would see (it’s encrypted), should you never give in to a higher authority that forcefully tries to see it?

Also, in the United States, the fourth amendment doesn’t work everywhere (every state), doesn’t it?
