I don’t think so, the ban is meant to protect the vulnerable sector, not to restrict people who gamble or those who are capable of gambling. I posted this because you used the word “reducing” instead of “increasing.” It won’t reduce accessibility, as it’s not restrictive.
It’s good that they have it in their country. Advertising is so powerful, and it should be restricted to people who should not be exposed to it, something our country has failed to adopt, which is why the gambling addiction increases at an alarming rate.
