I suspect that long term, if more states keep end up passing laws about this, it might drive people away from dedicated sites for this content and towards pages made for it on social media type platforms instead. These laws tend to stipulate that they apply only when a certain percentage of a website is adult content (for obvious reasons I imagine, if just one instance was enough to apply then they'd apply to basically any platform with user generated content, since people are inevitably going to try to post it), which leaves the very obvious work around of just mixing it into a site that also contains mostly other types of content.
Aylo (PornHub) is already a Canadian company. For a streaming site, though, you generally need servers hosted worldwide combined with a CDN with even more regional datacenters. Performance would take a noticeable dip.
