The better DMs and players I know share those responsibilities by default with the caveat that the facilitator/adjudicator/GM/DM/referee has the final say if it really comes down to it.
That's a fine way to play the game. It's not the way the books advocated playing the game though. It's been at least a decade since I cracked a 2nd ed PHB/DMG, but I sincerely doubt it ever suggests that the way to address something not covered by the rules is to achieve consensus with your fellow players, only calling upon the DM when neccessary. I'm pretty sure, however, that the basic rule of "if there's no rules for it, ask your DM" appears at least a dozen times.
