Can we PLEASE not have this discussion over and over again? The reasons for 
this default have been explained many times:
1. The default we ship is the default of the upstream synaptics driver.
2. Having tapping enabled can cause accidental clicks in several different
   situations:
   * at the beginning of a move (moving the finger to the touchpad too
     strongly),
   * during a move (accidental finger trembling),
   * while doing unrelated activities such as typing (accidentally touching
     the touchpad).
3. Touchpads have dedicated buttons (or areas marked as virtual buttons) for
   clicking. Why is another way to click needed?
(Reasons 2 and 3 are probably also why upstream does 1, so it's also 
pointless to ask upstream to change the default.)
