The question specifically asked which one(s) you are talking about, not about your dreams. Which high security value is the government not able to gain access to?
And, sure, if enough perfectly engineered vaults were impeding the government from carrying out the activities it wants to carry out, there would be calls to make building/using such a vault illegal too. In the real world, such vaults, if they exist at all, don't meaningfully get in the way. Thus there is no reason to think about it. We don't create laws on what theoretically might be a problem in some magical imagined world. We only create laws after something is identified as an actual problem.
