Excellent points. And I enjoy the atmosphere of watching a fight in person much more than watching it on TV. However....

1. Being there live doesn't always give you the best angle. Sometimes the fight moves away from you, and happens on the other side of the ring. Also, the ref can obscure your view, and there are no different camera angles to shake off the ref.

2. There are always several cameras available to record the action from the best possible angle. Plus closeups can afford a view you just can't get from several rows back.

3. Replays and slow-motion.... the ULTIMATE tools to judge fights.

Muting your TV can help eliminate the broadcasters' bias or misguided comments, 'cause admittedly many times they do more harm than good.
