So what about the fun and enjoyment which you can get in physical casino gambling ? You may enjoy the gambling with friends or family.
In online gambling which you may call it "Virtual Gambling" , you are all alone siting in front of your system. If you are happy winning or sad/crying losing, no one will know it.
This is the only thing why I gamble at physical casino's to have a bonding moments with my friends and have a good time. And I think most of us that is playing online will miss this kind of moments on the real casino's considering that, most of us started playing in real casino's before playing at the online ones.
The other that OP pointed out is all good and for me. And the no.1 factor why I keep choosing online casinos in random moments/all the time is the "Convenience", Anytime and anywhere you can gamble, and that's the biggest advantage of online casino's than those physical casinos.
