Ringoblack Regional events played at the same time would cause the TV networks a headache, so, I'm guessing that won't happen no matter how much sense it makes.
Yeah, this. TV is the force that dictates what happens where and when. Without CBS/NBC/Golf Channel, we have half the tournaments we have now. And honestly, I'm ok with that. Maybe I'm alone in this, but I find it hard to get excited about a PGA event every freaking week of the year. You've got the majors covering 5 consecutive months of the year. Mix in a alternate tournament split evenly between the majors, giving players a week off between a major and that event, and call it a Tour.
Sure, you throw the trunk slamming journeyman a bone and hold off week events with a top purse for the winner of $250k and a $1 million total purse from the sponsors. The main prize at these events is the 2 year exemption, and you pay enough money to make it worthwhile to those hungry enough who need it, to play and make a living.
But in this era of purses that can make a man rich enough to retire after winning one regular event, it's painfully obvious that money is no longer a driving force for the top 25 in the world. Heck, most of the top 10 are probably paying their expenses and banking a tidy profit just from the appearance fees they are generating. And that takes me back to the formative years of the PGA Tour, when Walter Hagen would show up anytime and anywhere, if money was being offered.
But if anything, we are oversaturated by tournament golf. The Olympics just made it easier and gave the top tier players an easy excuse to say, "no" without looking bad about it.
