As a supplement to Tekkerue's excellent answer, there are situations where it's very useful to know multiple voicings, specifically different inversions of the same chord for creating moving basslines.

Being able to change shape without changing the chord makes more of the fretboard usable for extending the range of the bassline as a separate voice.
