So why exactly would it be acceptable to assume that Yoda would condone and even train a Jedi to use a lightsaber, and yet somehow completely ridiculous that he might use one himself. That doesn't make any sense. So yes, it is just a matter of opinion.
So if a parent teaches their child how to ride a bike, that automatically means they themselves have to ride or even own one of their own?
