While I agree with your sentiment, in practice, relying on legislative options is not foolproof and is also a band-aid. You require a lot of human cooperation which, to be honest, is not trivial to achieve in 2019. Second, technology frequently outpaces legislative actions. You can relay a spam call/sms around the world and the receiver, her ISP or her government would still be completely unable to fix the issue. Honestly, I want disposable phone numbers (which are still compatible with public networks) something akin to email aliases. So if one number gets a lot of spam calls, I can just route it to /dev/null. We need a complete array of legislative + technological solutions.
