I think you're basically making an "it can't happen here" argument, and I wholly disagree. I worry this kind of thinking effectively guarantees it will happen here eventually, because it relies on dynamics that govern legitimacy remaining the same as they have been in the past. The way it would happen is specifically if the dynamics of loyalty and who has legitimate authority change, and we've seen over the last four years that that's 100% happening. The only question is how deep the distrust of institution goes and how far the people in key positions will go to defend a President they are loyal to. If you can convince enough people to distrust the process of picking the President, you can create enough chaos to break apart the forces that would normally counter that kind of thing.

Look at any nation that underwent major coups; factions form, and it tears the organizations you've listed apart at the seams. Because a conflict of legitimacy exposes those seams, and those seams are absolutely present today. A Secret Service agent, an army colonel, armed militia, border patrol agents—if they can be made to believe the results of the election are illegitimate, they may consider the best way to fulfill their oaths to be stopping the "illegitimate" president from taking office. They will think of themselves as the ones stopping the coup.

I'd love to believe that all of those dynamics you're describing are the same as they were 20 years ago. I'd also make your argument then. But they aren't anymore. It can happen here.
