Sidereal Time Is the More Fundamental Time, Since It Is

Sidereal time is the more fundamental time, since it is a measure of the true rotation rate of Earth. Why then do we govern our lives by solar time rather than sidereal time?

A) We cannot divide the day into 24 equal hours of sidereal time.
B) In sidereal time, the Sun would reach the meridian early or late, sometimes by as much as 17 minutes at certain times of the year.
C) Different clocks tick at different rates depending on latitude in sidereal time.
D) We wish to remain in time with the Sun's illumination on Earth, with high Sun angle at about midday every day.
