Lol, I think crop factor is far easier to explain than equivalence ! Maybe we don't know the same sort of 'beginners'.

Try telling someone why they don't get the same picture with a 200mm on their crop sensor that you get with your 200mm on your FF without mentioning crop factor !!!

Try telling someone why they don't get the same DoF with a 200mm on their crop sensor that you get with your 200mm on your FF with only mentioning crop factor.

Either tell them the whole story, or not.

Don't tell them half the story, because that is what really causes all the confusion.

And it really isn't that difficult. If you can properly explain the influence of crop factor on focal length, it is only a very small step to also explain them on the influence on the aperture setting and thus DoF.
