Those also occurred overseas. The government didn't already have control over the population like they do here. They didn't have massive amounts of data on every last person there, and everyone those people knew. They hadn't been tracking all of their movements. If the founding fathers had tried to gain independence while still in Brittan the fight would have been much much harder.

We can argue over how well a revolution might go in theory, but the second amendment's failure to protect our freedoms isn't theoretical. Our freedoms are being violated all the time. It failed. That means that having the "last resort" option doesn't prevent our government from violating our rights. The second does not protect the first.

A last resort isn't effective at defending our freedoms under the government we have. It just maybe gives us a very very small chance to throw the old system away and replace it with something new that would restore our rights.

Personally, I'd like to think that it's still possible to vote our freedoms back, but there's been a lot of efforts made to reduce or prevent our ability to accomplish that and recently voter suppression efforts appear to be escalating alongside talk of "third terms" and election canceling. It's certainty not encouraging. In my case, under an absolute worst case scenario, the most effective use of a gun would be suicide. At best it might save me from looters. I can't imagine it being any use against a drone strike.
