Sacraments are not merely "material." They, like the Incarnation itself, are a working together of the matter which makes up our world and the power of God who rules everything. Each Sacrament is a mini-Incarnation as God become present through the actions and material used in imitation of Christ Himself.
Would you be able to draw from His strength only, if you couldn't get your "fix" at communion?
Yes, but it would be foolish and insulting. Could you live off of tree bark, cork, and leather? Probably for a while, but you would be foolish and insulting to turn down a luscious banquet to eat instead the furniture, your shoes, and the coasters.

Enlighten us, Dave. Show us where Christ instituted these sacraments (other than baptism and the Lord's Supper) which are "mini-incarnations" of God. Show us also where God says that this is what they are.
While you have your Bible open, find where God tells us that any of these things infuse strength into a person.
