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.
That is why banning gambling activities will be just a nonsense act of the government because they cannot really stop the people from gambling because we are now in the time where technologies are so modern that even the government itself is still struggling to keep up and things will get expensive if they will exhaust some funds just to track citizens who are still gambling online or in-house casinos.
They are just wasting funds that could have some better use, they better think of regulations and not banning because the revenue that is generated by the casinos can be truly helpful to the country.
