> The US shows us right now that the constitution is just a piece of paper.

A constitution isn't just words, it creates a structure that exists in actual reality. The day before the tyrant comes you have multiple branches and levels of government. That stuff doesn't instantaneously cease to exist if they try to rip up the piece of paper, and its purpose is to fight against anyone who tries to rip it up.

If it fails at that purpose, your constitution contained insufficient checks and balances.(Notice that several of the ones in the original US constitution have been removed, and that was a mistake.)
