We can play as much as we want, as long as our own limits are respected, that is, we have a capital set up to lose, because it is what we have destined to play, that capital cannot be regretted if it is lost in the game , because it is known that it was destined for that, if we are clear about those things or those premises we can play with complete confidence and as we wish, but if the money is lost in its entirety, it must be respected in not Playing anymore,because if it is appealed to that Money is going to be taken that is destined for our daily expenses, be it for food, the market, for the family, it is what should never be done, basically it is to play responsibly.
If you play as much as you want, you are not limiting your self already. Maybe there are people who are not really in to gambling and they think betting minimal amounts for 20 to 30 rolls in a casino game is already too much for them but most people are not like that. They always can't get enough when it comes to gambling.
These people needs to limit their selves before it interferes with their life. Other than that, it will be better if your wife hold your money for you. If you don't have a wife yet, then you must still have your parents, or other people that you trust the most because once we see our balances, the temptation can always kicks in.
Yes , I completely agree with what you say, it may be that many do not control their way of gambling and that may leave them without money at a certain time , that is why I say if I have , let's say, 30usd willing to lose playing, I do it and I play with all the freedom possible, but without exceeding those 30usd, for me that is having responsibility, and it is as you say, when you have a wife, children, and you want to play in a casino , you should have even more responsibility, because you don't there is an excuse if someone spends the money that is earmarked for the expense of basic things or basic needs for them.
