Trump himself doesn't care about any of the details. He wants to hurt people he doesn't like, and he wants to be worshiped. That's it. There is no real "Trumpism" as policy. It's just, "Trump is the best", and the people who will do his bidding happen to be Republicans who bleat out that "government is the problem", a classic Reagan line.
Everyone else he surrounds himself with who are loyal are in it to destroy the US Government as an entity for good, so that their billionaire patrons can buy up the remnants for pennies on the dollar. The goal as always is neo-feudalism. Oligarchs want to be the founding member of an Aristocracy, and they need the US Government as a democratic (small d) institution dead. This is what you call unanticipated/entirely-intended Stage Two of Reaganism. Think Grover Norquist and his classic ""I don't want to abolish government. I simply want to reduce it to the size where I can drag it into the bathroom and drown it in the bathtub." That's the quote I was referencing in this current comment tree.
The parts of the government that will need to remain are the parts that allow oligarchs/Aristocrats to enforce their feudalism. Think spending on the military, and hey, look at the current Secret Police d/b/a "ICE" explosion in funding. NOAA? Helps people, fuck it. NASA? Helps people, fuck it. USAID? Helps people, fuck it. Dept. of Ed? Helps people, fuck it. Etc. Etc. Etc. These are all features and not bugs of modern US Conservatism. And fascism is just a stage to get from capitalism to feudalism, although I expect a strong Eco-fascism push in the 2030s and 2040s as the current destruction of the environment increases.
Republicans have spent 50+ years denigrating the US Government because their goal as Representatives of the Oligarchy is to break it down into pieces that can be bought and used as private concerns. They are succeeding, and they know damn well they have to run, not walk, if they want to make it permanent. Which is why Project 2025 was so thoroughly planned and now implemented. Nevermind Epstein, remember when Republican dog fuckers were screaming hysterically about how Trump and Project 2025 weren't essentially the same thing? The end goal has always been the same, Trumpism just gave Republicans cover to speed it up. And you can see other authoritarians and oligarchs around the world taking advantage of the US kicking itself in the balls repeatedly. You don't have to look any further than Israel and their amped up genocide that has been in slow motion over the last 75+ years.
Strike while the iron is hot? The iron is molten and the Oligarch's planned future of society has been molded. It's up to everyone who is decent as to how we get cast.
