You need a balance. You can’t have a government that can’t respond/change and you can’t have a government where whomever won the last election is now dictator whose whim is law.
A lot of this stuff was ripe for abuse since the beginning but it was only rarely abused so everyone just left it. Kinda how Vietnam war wasnt declared but went on for like a decade. The potential for that abuse of power was there since the founding days but wasn’t abused until much later.
As I said the states seem like they are moving away from it being an unchecked power so maybe one day there will be a constitutional amendment.
