My wife's uncle tried a coup, once. It didn't work out and he had to flee to Europe.
That country is a corrupt Statist hellhole, but a successful coup would have fixed very little (in the long term anyway). There had been others before.
A successful coup requires buy-in after the fact by powerbrokers. Not all of them, so its better than voting for different flavours of uniparty, but you can't hope to destroy the State while deriving all your power from it.
This is an awesome book on the topic, but longer on tactics than strategy.

I kinda know that it doesn't change anything, but it must be fun
