Some of us (like me) are just planning people (or planning machines, if you prefer). But I know lots of folks out there are spontaneous types.
As a planner who has all ADR's made for our upcoming January trip, I am glad that we are able to plan ahead like this, under the current ADR system. (And, yes, I confess, it is tempting to launch a triumphant "nanny-nanny-boo-boo" in the direction of the poor spontaneous types who are turned away from TS restaurants.

We planners often take a lot of guff from those free-spirits who call us geeks... and worse.)
I don't know what the solution is. But as others have pointed out, there IS always counter service, and it certainly needn't be a constant diet of chicken tenders and fries. Look at the menus from Tangierine Cafe, Tusker House, the ABC Commisary, just to name a few. People who don't make ADR's aren't going to starve. And there are grocery stores and off-propery restaurants as well, for those who prefer to go that route.
If WDW did hold a small percentage of tables for walk-ups, do you think it would solve the problem? Or would scores of people still walk away w/out being able to be seated?
Having said all that, I have to agree that 180 days out seems a bit far in advance.
