That's a sound argument, mostly (in the quote, i mean)

If the technical implementation of how they would try and force age verification was the problem people were concerned about, this take would be very useful.

Physical locks on glass doors are easy to bypass, doesn't mean you won't get shafted if someone just so happens to catch you in the act.

If third party age verification is legally mandated the implementation being technically difficult (or easy to bypass) doesn't stop it from being illegal.

Being a condescending prick works better if the position you take is unassailable, you do you though.
