1. Power corrupts. Giving absolute power to a central government will result in absolute corruption.
I don't know anyone who calls for giving absolute power to a central government. Think of it in numerical terms. Take federal receipts as a proxy for how much of the overall economy the federal government seizes for collective use at that level. For FY 2021, it was 18.1% of GDP. So, over 4/5 of the economy ISN'T going to the central government. Mostly, we're at the mercy of the private sector (with some also in the hands of state or local governments.) Would moving a little bit towards a public/private balance, similar to what we see in most other wealthy nations, result in absolute corruption? Isn't the current risk really more the other way -- that so much power is in the hands of private corporations that they're the ones most at risk of absolute corruption, and having a stronger federal government to hold them in check would do more to defend our liberties?
If you empower the Federal government with absolute power then what happens when another Trumpian asshole is elected to office?
Again, nobody is calling for absolute power. But, if a Trumpian asshole gets elected, we vote him out. We don't really have that same power when Trumpian assholes get too much private-sector power, since we don't get any vote there. If I think Rupert Murdoch exercises his power corruptly, I can't vote him out of his position at the head of Newscorp. It's effectively a feudal lordship, which he is set to bequeath to his heir. Something more democratic than that appeals to me.
Julius Caesar was only thinking of his present when he broke the Roman Republic and installed himself as a dictator
I think to some extent he was thinking of the past, with the Republic having fallen into corruption and decay, with corrupt politicians like Sulla abusing the powers of the state for their own benefit. I think preventing a Julius Caesar would have needed to start a lot earlier, with people like the Gracchi, who were murdered before they could force political and land reforms that would have helped the masses against the ultra-wealthy and ultra-powerful (people like Crassus, for example, who helped Caesar into power in the first place).
When the wealthy patricians defeated the reforms pushed by liberals like the Gracchi, they weren't thinking of the consequences such as Julius Caesar a hundred years down the road. They were just trying to preserve the prerogatives of the aristocrats against the dirty masses looking to use the powers of the state to spread the wealth of Rome more broadly. But they put the Republic directly on a path to collapse.
