Gambling can never be banned - it is the life support for the people and sometime it is very helpful for the economy for bringing in the revenue.
There is no question about the gambling industry helping to bring revenue to a country. But do not generalize that it's the "life support" of everyone.
However even in the countries where gambling is banned - now they have found the ways to gamble and there is no stopping. People would not let the gambling banned.
Because there is online gambling and there are many ways to avoid that restriction that they do even online. Users can bypass that restriction by using VPN and as long as the online casino, crypto or fiat allows that per user then they can easily gamble back and forth, at any time that they wish to do.
