The extraction of  the 24 hour/360 degree value from natural noon is

the 24 hour/360 degree meridians contain all the information about the
Earth's shape and rotation whereas the alternative and flawed value
cannot.

To which I ask, in yet another attempt to free you from your bondage
to pure rhetoric: why do geosynchronous satellites have an orbit
period of one sidereal day and why do they orbit at an altitude
corresponding to one Earth rotation per sidereal day?

I have to laugh at the 'pure rhetoric' part, the Earth rotates 69.17
miles at the Equator in 4 minutes and will rotate 24901.2 miles in 24
hours

I'll give you credit: you finally threw numbers into the talk. Good
for you. A small step, but an important one.

Unfortunately, merely looking up the equatorial circumference via
Google and claiming that a point on the equator moves that far in 24
hours will not give you an answer accurate to the nearest mile. If
you want to get down to the mile, you have to add the extra 68 miles
that point travels between 23:56:04 and 24:00:00.

If you'd use your Googling skill to look up the orbital elements for
any geosynchronous satellite of your choice, you'd see that they all
have orbit preriods of 86,164 seconds, plus or minus a few ones of
seconds.

Think about what the term geostationary means. Stationary with
respect to the surface of the planet.

denoting the accurate value for maximum planetary
circumference,whatever value you come up with for 23 hours 56 minutes
04 seconds I neither know nor care

You're being disingenuous.

Stick to the math. Math doesn't lie. Ever.

That's why scientists--e.g., /real/ astronomers--like it so much.
