Banning Internet gaming
IMHO, the big problem with internet gambling is the current difficulty in regulating it.
Think of all the sham operations that have come and gone, and gone with all the players' money.
Look at the withdrawal policies of even the "good" ones (e.g., Casino-on-Net). Sure, they'll TAKE your money instantly, but look at the hoops you have to jump through to get any of your money back.
The internet itself, by its very nature and structure, virtually defies any form of effective regulation. Ergo, IMHO, internet gambling becomes equally difficult/impossible to regulate. Ergo, it should be banned until/unless some means of effective regulation and policing becomes technically possible.
In the meantime, the public will just have to be satisfied with betting on the stock market .
