StarCraft is a strategy game but it's also an action sport. The "how" of micro actions is largely the sport itself, both from a decision-making and execution standpoint. Imagine a footballer having a "kick goal" or a "kick ball past goalie" button -- it'd largely defeat the purpose.

I believe the command spamming /u/tomlock is referring to is the phenomenon where players issue as many or more commands when doing nothing as when an intense sequence is happening. This is primarily done to keep rhythm.
