The bushing/collar is needed because aluminum (which what the lever generally is made of) is a soft metal and will wear down quickly. That bushing is made from harder material, maybe brass or whatever which takes more to wear down.
If you don't have that bushing in there, the hole will grind away and get bigger making unsafe conditions for your clutch lever.
So yeah, you'll need to replace that bushing sooner than later.
