I agree. And strangely enough, it seems that Trump’s lawyer kind of agrees too. (i.e., they say the order is not necessary because there are already laws against those things - obviously they don’t say that Trump should be locked up though!)

I have heard someone justify the court order in a way that kind of makes sense to me though. The rough idea is that although there are laws against threats and intimidation, any incident of those would have to be prosecuted separately from this current case. It would basically require a new case to started, with another prosecutor etc. and in the end, that case may or may not result in a victory. All that can still happen; but the benefit of the court order is that if Trump continues the threats and intimidation, then the judge can immediately hold him in contempt of court without having any additional steps. So, it may make the process faster and easier.

All that said, I’m giving you my non-expert recollection of something I read from some random person on the internet who probably is also a non-expert. So it’s probably best eaten with a barrel of salt; or possibly not at all.
