Remember, it's always easier to destroy than create. This is true even for bloated parasites pretending to be federal institutions.
All these grant programs, these federal agencies, these swamp creature dens? Recreating them won't be as easy as the next Democrat just waving a wand and EOing them back into existence. Budgets will need to be created and signed off on by Congress. People will need to be rehired or hired anew, which includes background checks, security clearances, etc -- and they might have moved on. Network connections will need to be spun up ("We're getting contraceptives going for gay Pandas in Japan, so we need to get a line of communication with one of our activists in Tokyo University... Wait what do you mean they left after we cut their USAID funding?"). Infrastructure will need to be created and updated.
I don't know if they've realized that yet, or if they think they'll just be able to flip a switch and restore these slush funds the second he's out. But in reality, the damage he's doing will probably take an entire Democratic administration's time effort and political capital to undo across 4 years -- or more! Worse if he keeps bragging about it publicly and the Republicans make damned sure to start raising holy hell if they start trying to "undo the anti-corruption measures we worked so hard on."
Regardless, their plans for whatever happening around 2030 are well and truly fucked now.
