Good comparison.
We are old enough to gamble which means we are old enough to make our own choices. Those who blames the online casino for having a bad day in gambling are those who doesn't really understand how gambling works. It's a business, we should not forget about that and what they want is to make money, not to give them easily.
It's better if we understand those facts so that we won't be expecting too much when we are playing. Expect losses, that's better.
