Passing new ones that "you like" requires lawyers to write laws, get those laws in front of reps, get them to agree to try and pass it, stake some of their reputation on pushing it, get the ground swell to support it -- which might be difficult when the current law is "dont scan messages", you can easily say "hey dont scan anything! support that!" vs "hey scan somethings sometimes", cause many people will call that a slippery slope. I don't see how they are at all the same process.
