They don’t have more power. Whoever is telling you that has been lying to you, starting with the idea that these are lifetime jobs or lack accountability.
The American system of government is based on checks and balances between the branches. Congress passes laws which delegate some power and the Executive Branch implements them. In many cases, the high level positions are presidential nominees who are mutually agreed upon with the Congress and serve a set number of years or until recalled by one or both parties. Each agency has specific rules governing what they’re allowed to do and how they do it, as well as oversight and transparency for their actions.
What we’re seeing now is the conflict caused by Republicans deciding that following the law is too hard and creating conflicts with people who are following the law. When Musk was pushing people to grant access to restricted data, for example, it was proclaimed as disobedience but was simply that the people charged with protecting that data do not have person discretion in that matter: the operator of a SCIF knows they face heavy consequences if they allow unauthorized access. In all previous administrations, this hasn’t been a problem because people just waited a few weeks to get clearances.
Similarly, when Trump illegally tries to fire inspector generals it isn’t that there’s no way for him to do that, he just didn’t feel like giving Congress 30 days notice.
In all cases, the law is what matters: if there is a real disagreement about how one of the independent agencies operates, Congress can change it at any time and given the Republican majority it would not be hard for any reasonable change to be quickly enacted, at which point an agency head would be removed or even prosecuted if they fail to comply.
It's interesting you invoke the constitution and law here when law is being violated per the constitution - funds are being unilaterally revoked by unelected individuals, funds that were voted on by congress. Congress has the power of the purse. Weird you leave that little tidbit out of this whole screed, it's almost like you're being purposely dishonest.
