If similar to equivalent state regs, when access to customers residing in that market is gated by compliance and subject to lawsuits or ban, the first phase of business-side operations change is immediately setting up minimum compliance workflow like a special webpage coupled with countermeasures (like proof of residency; IP historically difficult in court but has been used successfully for state-specific age gating) and boundary testing cycles. With especially large markets, however, the overhead associated with maintaining multiple separate workflows fails the efficiency test and the workflows are merged, which is how everyone tends to benefit from pro-consumer laws like GDPR.
