Absolutely ridiculous notion in the OP. Competitive chess is played with an increment or delay because the game isn't supposed to be decided by the clock.
That clearly is not the case fpr blitz, where the standard OTB time limit is 5 minutes with no increment and the clock DOES decide the game in many cases. USCF rule 5C. Ratable Time Controls includes, "Standard blitz uses no delay or increment," although 3/2 is allowed.
So your "absolutely ridiculous" is both wrong and mean spirited.
Why? Everyone can play however they want. I prefer 3/2 from 5 0
