If a gambler wants to abide by the rules of gambling governing his or her country, they can do that. But when we have a set of gamblers that are already addicted and cannot control their addictions, any rules set for them is always beyond what they can abide by and will look for other means to get their urge for gambling satisfied even if it means them doing it the illegal way. They can still use VPN to access some gambling sites outside of the country if they use casinos that allow the use of VPN. Going extra miles to travel out of the country to satisfy their urge is a big sign of how addicted they are as a gambler. Gamblers like that needs to check and control themselves at this point.
