Humans used the suns position to reckon time since times before history, fair enough. But only because it was the best they had. At every turn since, where a better method have been discovered, it has been applied instead. In the later half of the 1800's were mass produced clockwork became widespread, people relied on the clocks even though they were later (se below) found to have no precise correlation to earth rotation angle, but tended to be set to whatever the locals preferred. With the advent of mass transportation in the shape of trains, this was found to suck, and using the new electric telegraph, the clocks were synchronized to whatever degree possible. Since that point in time, the clocks have been synchronized to whatever the proper authority stipulates, with no regards to solar time, mean or otherwise. Dropping leap seconds amounts to the central authority adopting the same method of time-counting as everybody else uses, and has used since the dawn of history: 24 hours to a day, 60 minutes to the hour, 60 seconds to the minute. The suns position in the sky has nothing to do with this, that is in the hands of the local(-ish) politicians who legislate your timezone. So yes, leap seconds were an means to an end, and now that astronomers have had a further 40 years to catch up with the mechanization of time-reckogning, it is time to drop that hack which handicaps everybody else.
