We should take gambling as it is because we have to make fun in it and this should be allowed for everyone to use, there is no sentiment over whom should gamble or not, we all have the entitlement for the opportunity to gamble and have fun, but when we are doing this, we must have a limit to what we should do and what we shouldn't, because in everything, abuse could be avoided only when precaution in taken into consideration.
Yes, everybody can gamble, but not everyone are gambling for the reason of them wanted to get entertained.
I agree with what you said that we should gamble "ONLY FOR FUN", but not all of the gamblers out there have that kind of thinking.
Unfortunately, there are some gamblers out there that are gambling for the sake of money and they're the ones that are prone to huge losses. Always have a limit and to add to what you said, don't gamble if you don't have spare money to be used. Don't use the money that's been allotted to something for gambling hoping to make more money. We can all gamble yes since it's accessible for everybody, but not everybody has the spare money that we can use for gambling. Priorities, mindset, proper thinking, discipline. We need those before we gamble.
