Keith, I love golf, and I love the Olympics. I could care less about Olympic golf, though.
By its very nature, the field will be weak. Even if everyone eligible took part, tons of top players would be left out. That alone makes the event pretty much a joke to me, at least as a serious golf competition.
Also, the Olympics interfere with tournament golf far more than they do any other sport I can think of. Tour golf holds some of its biggest events right during and around the time of the Olympics. Not true of tennis, basketball, swimming, track & field, soccer, gymnastics. For most sports, in fact, the Olympics IS the premier event. For golf it's a side show, featuring a weak field, no tradition, no purse and security risks (already several athletes who went to Rio early have been robbed at gunpoint).
We don't ask the world's best baseball players to break away from their season every four years, so they can take part in the Olympics. Golf seems to me similar.
Then there are the health issues. The CDC has issued travel notices about Brazil: it considers Brazil as a country with epidemic Zica. Any man who gets infected can pass the disease to his wife, gf, or anyone else he has sex with. No one can quantify the risk, but as the CDC says, "The Zika outbreak in Brazil is dynamic."
I also think Tom Doak nailed it about telling other people how to live their lives.
