The question is how you put the genie back in the bottle.
I think this is the core insight of small-government conservatism. When big, powerful institutions exist, they can do great things...provided they're always run by exceptional people. But when they're not, the damage they can do is incalculable.
So the question becomes, how do you create a system with the best long-run survival properties? I, I suspect much like you, would like it if there was some way we could return a bit of power back to Congress and other institutions, and away from the huge executive we have today, in 2020. It just feels like a ticking time bomb until the wrong people get the helm.
