Just like when we went through this sort of hyping up the threat in the dying days of Trump, mainstream perceptions of power matter, they massively affect how much power someone actually has in practice.
Just like that occasion, it is true that we cannot completely exclude the possibility of him trying to pull some stunt. But such eventualities are not the most likely outcome, more likely is that he really has loads less power and wont even be able to do all of the things previously announced (eg channel 4 privatisation is being touted as an example of something that may not now happen).
Even when people whose power has drained away are still surrounded by relatively weak people, the chances are that those people and the system will find it much more easier to restrain the figurehead, will find it easy to stand up to any attempts by the figurehead to make use of power that is not actually available to them any longer.
I've got a vague memory that I had this sort of conversation with you during a particular stage of the end of Trump.
