All the arguments you made applies to VPNs or tor as well. I'm sure rightsholders would be very happy if VPNs are banned, because that gets rid of one avenue for pirating with impunity. Same goes with every ad network ever, which has to fight click fraud.
How exactly does that also apply to VPN or Tor?
Who's using VPNs and Tor to blend in their automated scraping traffic with real human traffic?
Who's using multiple VPNs or Tor exit nodes to avoid rate limits?
No one, but I would have no problem with that being illegal too.
