He does have word-salad issues.
But he also typically repeats the last thing that's been said to him, without understanding the implications (hence his "using bleach internally" press statement during covid).
Him saying this comes hard on the heels of Jack Prosobiec standing on the stage with Steve Bannon (Trump's former and possibly present puppet-master), saying "Welcome to the end of democracy", to rapturous applause at CPAC.
And the Project 2025 document is a road map of reducing democracy – eg where senate or other oversight is required for appointments, just appoint an acting head.
There are legal restrictions on how these acting heads can be appointed and for how long, but as we've seen, it's lifelong Trump strategy to just keep kicking the can down the road for one more day and make hay while he yet is able. It's very effective and is serving him very well even now, with the major legal cases not yet resolved against him.
And an acting head may themselves make rule changes about how appointments can be made.
Eg this document describes the restrictions – and gives an hint of how much had to be rolled back when it they were breached:
Understanding the Federal Vacancies Reform Act
September 9, 2020

The opinion on acting officials at DHS released by GAO in August involved a situation where another statute overruled the FVRA’s default succession rule. The 2017 National Defense Authorization Act allowed the secretary of homeland security to designate other officers at the department to serve as acting secretary. In 2019, Secretary Kirstjen Nielsen used that authority to lay out two different succession plans, one in case of resignation and the other in case of unavailability during a disaster. GAO found that when Secretary Nielsen resigned later that year, DHS followed the disaster plan instead of the resignation plan, and consequently Kevin McAleenan incorrectly took office. McAleenan introduced a new succession plan to allow Chad Wolf to become acting secretary, and then Wolf altered the succession plan to allow Cuccinelli to become the director of USCIS. Because McAleenan originally took office based on an illegal succession, GAO decided, the subsequent succession plan changes were voided, and both Wolf and Cuccinelli were serving illegally.
