That goes to another tactic we’ve seen here a lot, the Nirvana Fallacy of Gun Control.*
Claim: [Proposed gun control measure] won’t be 100% effective in reducing [negative outcome(s)], therefore we shouldn’t do it at all.
ETA: people who use this tactical sometimes come up with weird theoretical edge-case scenarios to support it.
[* Pedants will call this a perfect solution fallacy, but this has a nice ring to it]
