pick or fingers?

so what's wrong with using my fingers to play the blues? bass players use their fingers. you've got fingerstyle acoustic guitar. what's the big deal about picks? i know they make a cleaner sound, but in a way a pick just gets in the way between the player and the strings. why not use the fingers to manipulate strings?

albert collins used his fingers. he also used a capo, played a fender telecaster, and put the strap on his right shoulder. weird guy, but it worked for him!
