What specifically are you disagreeing with in the quote? It does not say that Google is five nines, nor does it say whether or not five nines is desirable.

The argument is basically the following:

(1) Consider the claim that getting to 100% reliability is important.

(2) If the claim were true, then it would be important to go from 99.999999999999999% availability to 100%.

(3) That is obviously not important, so the claim must be false.

(4) Since we have shown that the best target value is not 100%, it must be some number x, with x < 100%.
