Why would there be a benefit from running without the 02's? Isn't this going to hurt the function of the MAF?

You act like you've never done this before. Everythime you have turned adaptive off, you were essentially disconecting the O2 sensors.
Basically, you would just put the ECU into open-loop operation all the time. For this reason, you would have to have your tune dialed in perfectly. Also, any changes over time in your set-up would never be compensated for and end up causing your tune to be off over time; things like dirty sensors, increased oil consumption, etc.
It may work fine for a race car, but I think a street car would suffer in the long run.... not to mention fuel economy would never be near what it should be.
