Squak
Of course I agree with you that we should all be able to do a visual. I feel very confident that I could do one on a nice day anywhere you like. Fact is when our finest aviators (Training supremo's) delivered 744's to Kemble in UK for the aircraft to be broken up, they did a couple of hours of practice in the sim prior to carrying out a non ILS, non PAPI visual approach.
SFO has several runways that have ILS - just use those for goodness sake.
