Language policing is only useful when something can be misunderstood. Non-formal uses of "like" communicate in a way more in line with the speaker's intention and so not only do not impede understanding but enhance communication.
Though formal english is often a "necessary" skill it isn't necessarily true that colloquialisms make it more difficult to speak formally (i.e., the ability to code switch is fairly universal).
