Your argument is that because the 4004 was built to power a calculator that disqualifies it as a microprocessor? Independent of the actual nature of the 4004 itself and its potential applications beyond its first intended use? Can’t see how that makes sense at all.
Your statement about Intel 'pushing back' the date to 1971 also makes little sense given Intel advertised [1] the 4004 as a CPU in Electronic News in Nov 1971.
