"His point was that if you ever get into an accident and the first responders have to cut your ring for whatever reason (MRI machine, etc.), literally none of their tools would be able to do that on a titanium ring"
As a somewhat-experienced jeweler, titanium is not terribly-difficult to work. It's a pain to solder and weld (I use it for wire-wrapping in various gauges,) but cutting it is relatively easy, a good pair of hardened-steel thick wire cutters will absolutely shear it.
