Second Amendment arguments, like biblical arguments, get very loud and prove little other than the arguer's interpretation of something that was written long ago under vastly different circumstances.
Sometimes, courts make an honest and unbiased effort to determine whether new laws are consistent or inconsistent with our Constitution as amended. Other times, courts prefer to apply politically influenced standards of interpretation. Both liberally biased courts and conservatively biased courts have existed in our history. We are now in an era of conservatively influenced standards of interpretation, and likely will be well into the foreseeable future.
The above means that new laws intended to curb private gun ownership stand little chance of holding up in court nowadays. Gun ownership is likely to continue growing for that and other reasons.
It is my guess that gun owners as a group would profess to be more patriotic than those who do not own guns. Therefore, I see gun ownership as a perfect starting point for a "buy local, buy American" resurgence. If you're going to buy a gun, get one from a licensed local shop. Get one made in America from American parts. Hire a professional to train you. Practice regularly in a safe place. Act as if you belong to a "well-regulated militia", in other words. Walk the walk.
