It is our sole instinct to survive at any cost. To prove ourselves superior, that we may survive, at any cost. The ultimate goal of all creatures is to become the most sucsessful, the most superior over all others. It is why we kill, why we lie, why we tell tales, argue, and by our own human intelligence why we can sometimes throw ourselves willing into death to save others. Humans are only now starting to become sucsessful as a whole, not as individuals.
The golem was our slave, our attempt to be superior with no equillibrium, no cost, We suffered for it. In the legend of the golem, by erasing the first letter of Emet(truth) which was written on the golem's forehead, thus spelling met(death) and killing the golem.
There Is always equillibrium, there is never an easy way.
Oh my, I've gotten off topic
As for the concept itself, I have my own reasons to beleive it is entirely possible to make something out of pure will. The problem is that our own will is so bogged down with law, it is seldom, if ever pure.
