How is a legal process a coup? For readers which aren't sure of the definition of coup, "a sudden, violent, and illegal seizure of power from a government."
I don't see how an impeachment inquiry (even if legally a bit vague) as "violent", "sudden", or "illegal", nor is it a seizure of power, since it is just an inquiry.
If you want to argue that ordering witnesses for investigations without first declaring a formal vote on an impeachment inquiry is illegal, you won't find the Constitution or CRS reports state that a vote must be held for such orders to be valid.
Many of the undertakings that happen at the state level require a functioning federal government for them to go anywhere. We do not have a functioning federal government, so here we are.
Our federal government works shockingly well for its size and scope. Dealing with the State Dept to replace a passport at the last minute was one of the best customer service experiences I've had in years.
The parts that are not functioning are the legislature and executive branch.
You're right. It would've been more correct for me to say the part that works well is employed and non-political, while the dysfunctional part is composed of mostly elected officials and their appointees.
That the tech industry has been a primary player in enabling this.
Each and every one of us needs to have a nice long think about our own ethics and what we're willing to support.
