My suspicion is there are three difference reasons.

1) You may not solemnize marriages because you don't have a grant from the state saying you may solemnize marriages. It is a western tradition that "clergy" have the right to solemnize marriages of their own. I've never found any biblical support for the practice.

2) Administering the sacraments is for ministers of the Word only, since preaching and the sacraments go hand-in-hand in corporate worship. This has the strongest biblical support of the three, IMO.

3) I suspect this goes along with who may conduct public worship services, but seems more of tradition that apostolic directive. I see no reason why any officer could not offer a benediction, although I also see no necessity for a benediction per se.
