Newtonian physics was observed, modeled, and predictions were demonstrated accurate. Until Relativity and Quantum Mechanics showed us that our models were too simple. This whole argument you're making that things are "concretely falsifiable" is still entirely about trust, and faith, and "good enough" in practice. It's nowhere near as rock solid as you're portraying it. With guns, if you can't even agree that reducing access would decrease gun violence, it's hard to then debate whether we should, and whether we would need to modify the Constitution in order to do so. We can't even start the conversation. "Abandoning the gold standard was good" is theoretically falsifiable, but you'd need to explore the multi-verse, or you'd need to run grand experiments in other countries. (Other countries DID do that for us, and it was bad for them.)
