What would likely happen is VPN providers would be IP banned but people could still setup their own custom VPN solutions as that's hard to ban without banning corporate VPNs? Of course my fear is as this idea spreads VPNs and even Tor will become increasingly useless as all exits will be age gated and censored as well. This is something where technical work arounds will only work in the short term, laws like this are a slippery slope that we seem to be sliding down.
