Well depending upon which source you want to follow and what you want to infer, the concept and implementation of Time Zones was to make it so that "noon" was the "middle of the daylight" regardless of where you were on the globe. At some point, at least in the USA, the railroads got involved and farmers wanted the activities that they had to do in daylight to occur when "clock bound" people were awake.
If you say you want to maximize the amount of "daylight" between 6 AM and 6 PM local time, DST is one way to accomplish that. You are not creating or saving daylight but you are manipulating when the clock says it is available.
In 2018 it can be argued that maximizing the amount of daylight in an interval is no longer necessary and may be A Bad Thing because of the way the shift effects a human's biological clock.
