Here's the problem with your very long babbling.
The original intent of the Second Amendment (and the Third Amendment) was to define and limit militias.
The original proposed text of the Second also allowed for contentious objections on religious grounds for being conscripted into a militia. This was a big deal at the time, because you had groups like the Quakers who objected to military service. It was rejected because that would limit the power of the militia. The third was meant to limit the militia... it wasn't just about putting soldiers in people's houses, it was about having a permanent militia presence in communities in peacetime.
The problem, of course, is that these original intents have been lost, because militias have been replaced by professional Armies and Police Forces, with the police become far more militarized than in the worst nightmares of the founders.
Of course, it was never about gun ownership. Gun ownership was actually relatively rare in colonial America. There wasn't even a domestic gun industry, firing mechanisms had to be imported from Europe.
The founding fathers believed in Well-Regulated Militias, and at the time, each state had reams of laws defining the militia, with everything from uniforms to what the standard weaponry should be. (Again, you can't do logistics for a militia if everyone shows up with a different caliber gun). What they didn't believe in was angry mobs with guns, which is why "popular rebellions" like Shay's Rebellion and the Whisky Rebellion were put down.
