Hm, I kind of agree with some points from OP and disagree with others.
Ultimately I think life needs to be a balance of doing things that make you personally happy and things that help others or make other people's lives better.
I think there needs to be more to poker than just grinding and living like a 'baller' etc. I think if you only play poker to get money for booze, parties bling cars and things only for yourself then yes you could say that is a waste of a life, sure you enjoy it on a hedonistic level, but contribute absolutely nothing, if anything you'd make a negative contribution to the world with the money you take and fail to use in a constructive way.
However, say you make a lot of money playing poker, and use it to raise a family with children who can think in a conscientious and empathetic way and to contribute more good than bad to society then that is a really good thing. Or if you use the money to buy nice things for other people, people you know, people you don't know, homeless people on the street. Donate to charity and so forth.
I think poker is just a means of fun for some, and the fact that can also make you money complicates this.
The money side is in my opinion just like life. As long as you do more good than bad and as long as you make the world a better place, even if only by just a tiny bit overall, then there's no reason you shouldn't be able to enjoy yourself as well, often you will find you're able to do both. Maybe this is not the case with poker, but it can definitely give you the capacity to do good things through the money you make from it. Also there is a nice sense of friendly competition in a lot of live poker too, usually people are just there to have a good time, not win cash. Especially for the losing players, it is mostly not about the money.
And WillyD, I'd say there are 7 billion types of personalities. You're against generalizations but those 140 personality types would definitely be generalizing.
