Why is taxation/subsidies a better method of adressing externalities than price controls/min wages/price ceilings ?

In an ideal situation, taxes and subsidies simply shift a supply or demand curve and cause a change in equilibrium while price controls just force a restriction on quantity supplied or demanded by setting a price. 

In reality, there are times when taxes may or may not be more useful, and price controls may or may not be more useful for a desired economic outcome.
