You could argue that, but I think it's still a pretty weak argument. Arguments in favor of gambling as recreation are similar to ones made in favor of drugs as recreation where you basically just burn money in exchange for chemicals that make your brain feel good, but with few other benefits.

Whereas other forms of recreation (IMO) give you more in return, such as increased dexterity, increased knowledge, strengthened human relationships, an interesting story to ponder and discuss, etc.

I'm not saying people who gamble or use drugs are bad, I'm just saying the value of a given recreational activity can be measured along more axes than "dopamine yield"
