This is what I assumed the answer would be, and at this point it just becomes a difference in opinion. I personally do not believe that the methods you describe are generally acceptable options in the modern age. My phone number and address are much more important to me than the off chance of someone capturing my https traffic, breaking it, and inserting a fake public key. There is a point where the absolute security of exchanging public keys written on pieces of paper in a park are called for, but it's not for everyone or even most.
