Because you're not going to perfectly match the speed, and the synchro has a bigger job matching the transmission input shaft plus the massive flywheel and rotating assembly of the engine than just the free floating input shaft and friction disc of the disengaged clutch.

But if you think you can do it better without the clutch than with it, go ahead, wear it out. Don't come back here later complaining about Toyota's low quality transmission that tore up.
