First, what people are asking is not just a left-click interface. More correctly is to call it a left-click-does-it-all-and-right-click-just-deselects.
I'll explain somewhat better why the actual system is better.
At the moment, left click selects and right click does the default action.
Changing it to the other system may seem not a big diference but it is.
For example, default action for units regarding friendly buildings/units is the guard. Pick you constructor and just right click on building. Pick you brawlers and just right click your commander... Pick your transport plane and just right click your target to load it.
And, if you instead want to select another unit, left click is right there for it.
With the other system you're stuck with: pick whatever and when you click the target, you select it. For the examples above, you would always have to specify the action (Guard button/'G').
Optionally, left-clicking would do the default action but then, everytime you wanted to select anything, you would probably want to deselect whatever you had selected.
How many times have i given a move order to an entire army when i was trying to select a unit and clicked in the wrong place? Tooo many!!!
If people still don't understand or still don't want the system... whatever.
