Except....the airplanes in question aren't crashing because it was built by randos. They're crashing because of spatial-D, as are production aircraft in the other accident threads that resemble this one.
Now, if you mean your strawman framing as the pretext they'll use to eventually corral EAB out of the sky? Yes, of course they'll use that as a low-hanging fruit.
If people sincerely cared about saving the children, they'd be gunning for pilot certification anyways: Outlaw the instrument rating at the private level, make IFR access post-commercial only. Furthermore, make SPIFR a separate endorsement/qualification within the CPL-IR umbrella. The lower-level/default privilege would be the 'crewed flight' requirement; SPIFR would be the higher-level endorsement.
Now we're all safe. Most importanly, you just grounded most of the weekend warriors (real or fake/financed rich alike) who resemble the remark, given the desired use case that drive ownership of these contraptions in the first place (e.g. not the anemic, vomit-wing-loading LSA go-kart use case). Yai safety. /s
