The question is enforcement, not " destroy you."
You describe a system where extrordinary discretion occurs ( if Dershowitz is right).Discretion not to prosecute.
Government does target, but rarely people of wealth and power directly from an incoming regime.
Maybe you didn’t notice:
Everyone who had a Trump related investigation tossed on their desk has been ruined by the machine.
IGs who do real oversight are fired because they are not biased and loyal( currupt from an IG standpoint)
Witnesses who were nearly lifelong diplomats, decorated vets, destroyed for testifying truthfully under oath.
And pure power giving special treatment, like Flynn.
