Given that the only way for those websites to block VPN traffic is to block the IP addresses of all known VPN exit points, what you would see is first the commercial VPN providers regularly rotating those IP addresses of their VPN server exit points, and second people simply setting up their own VPN servers software in rented VPS machines in cloud providers anywhere in the World to run their own personal VPN.
You don't really need a full blown remote session, just a VPN server in a machine (physical or virtual) with an IP address which isn't yet blocked by such a site.
Now, the sites might try and block this by only allowing in connections from blocks of addresses which are known to belong to ISPs (which would theoretically only be direct connections from individuals, so not using a VPN), but that's way less reliable than merelly lists of IP addresses of the VPN servers of big providers, plus it would block thing such as the entirety of Amazon AWS.
Theoretically the sites would have to block all IP addresses of all cloud providers, including massive ones such as Amazon AWS and Microsoft Azure, because people in Wisconsin can just run VPN Server software - which is side of the VPN were the network connections exit the encrypted tunnel and enter the Internet - in a container or virtual machine inside one those to have their own personal (or shared with whomever they want) VPN.
Similarly they would have to block all exit IPs of most companies because somebody in Winsconsin might be using the VPN of the company remotelly go to their company network and via that network access those sites and which point the connection will probably appear as originating from one of the company's routers because of NAT.
The way the VPN technology works, theoretically every single IP address on the internet might be an exit point of a VPN which is being used by somebody in Winsconsin to access one of those sites, since one can even run VPN Server software on a mobile phone or Raspberry Pi.
Theoreticaly those sites have to block every single IP address which might directly or indirectly be used that way.
This law is completelly insane.
