There is oversight and limitations. The government still needs a search warrant or legal ownership of a device in order to hack it. You're perfectly entitled to make your stuff harder to search, but once the government has a court order or warrant for the info, they're entitled to all the hacking they need to extract the data. Stop and think for a minute about what you're proposing, that the government need to now get a second search warrant for the removal of encryption. That's absolutely ridiculous. If they seize a safe from your home, they don't need special permission to crack it open.
