This is a statement, very strongly worded, that is testable. We can measure your claim about the framer's intentions against their actual intentions because of how thoroughly documented the Bill of Rights and US Constitution were debated by the states before they were ratified. Also, the contemporary documentation surrounding the discussions around "the right of the people to keep and bear arms."When exploring original intent, the Founding Fathers were worse than the NRA on their gun-freedom, gun-loving. Some contemporary interpretations of the Second Amendment meant that the people were required to own arms, maintain them, and be prepared to serve and defend as needed. That's quite far removed from the modern interpretation of the Bill of Rights. That's a violation of the first amendment: forcing the people to keep and bear arms. Remember, there were peaceful people, religious people, pacifists, that were colonials. Highly unlikely that the group of "required to be armed" people got much tractions.
Not only were arms allowed to "the people", meaning every single denizen (not citizen, denizen) was allowed arms. Bearing arms was viewed as such an essential right that Thomas Jefferson compared it to fire, food, and water.
Just read how this eloquent man put it:
He's...almost as wordy as that Skywalker Star Wars kid but far more eloquent.
Regardless, to get to the bottom of your statement about super powerful weapons: did they intend "The People" to own highly destructive arms such as bombs and cannons? Or, as you worded it, "the right to any and all weapons." Can a private citizen own a surface to air missile under the Founders' interpretations of the Second Amendment?
Why, yes, you can! Private citizens often owned cannons especially merchants. This included missiles that delivered explosive payloads: similar to but very primitive compared to your surface-to-air missile concept.
Also, and quite often, the people who had the right to keep and bear arms were referred to as "free men." Why? Because one of the most famous examples is of a private citizen owning a friggin' warship (armed to the teeth and certainly among the most powerful offensive weapons of war around at the time) was a black man, a free man! So, yes, the intention most certainly would have been to allow the private citizens to own cannons. If you interpret that to mean that a private citizen can own a surface-to-air missile and launcher, that would be within the original intent of the Founding Fathers. Types of grenades were certainly a thing, then, too.

I highly doubt any of you will genuinely read this post, make the effort to understand US History, and make the effort to understand Original Intent for the US Constitution. You will only take out of this conversation what you feel represents your position. Which is stupid. Some Authoritarians don't even participate in the liberal and libertarian debate about the right to bear arms: they want to repeal the Second Amendment because they know full well that the Second Amendment intended to arm all denizens. While deplorable that they would seek to remove the people's rights (bastards, the lot of them!) but not actually do anything to stop intentional homicides, they are taking the correct approach.
