A government led by people considering themselves above the law, utilizing their position to enrich themselves and their family at the cost of the rest of the country, while also giving rise to the rebirth of fascism - isn't this what the 2nd ammendment was made for, to prevent tyrannical rule? Isn't preventing this exact thing from happening why the gun proponents claim to have their weapons?
If your population cannot field enough militiamen to this threat to your republic, and walk on Washington, you might want to re-evaluate your arguments for gun rights. If you've got a gun and you're not willing to march against the tyranny in your own back yard right now, then why do you even own it?
Sure, there's self-defense weapons, which can be kept at home. Sure, there's hunting and sports, which can be kept in a gun locker or at the club. But the rest? Either walk against tyranny, or admit you're nothing but a gun fetishist using the 2nd ammendment as a cover for your lust.
