Yes, at least with the right guardrails. The fact that my law abiding neighbor can own a grenade launcher (You actually can legally own a Grenade Launcher with the right paperwork) wouldn’t bother me any more than an aggressive SWAT cop doing a pre-dawn raid on someone’s house. If you want to own anti aircraft weapons sure, maybe with a license and a background check. If spending a few million $$$ to explode things in the desert is your jam you should be able to do it. Maybe you could even open source it and help develop better weapons for people in Ukraine or whatever.
