The problem with your license is the subversive use of its terms.
Although it may be reasonable to expect future contributors to have read SICP, installed Gentoo or fucked themselves at least once, it doesn't do well to restrict these terms for commercial or political enterprise, as it does not help guarantee the intention of the work; nor is it made clear to whom the evidence satisfying those terms may be presented.
Say for instance, a compliant contributor towards a derivative work may have the ulterior motive of collecting said evidence for commercial or political reasons.
So not only do these restrictions not protect the work itself, they expose a loophole to be abused for the very thing the license attempts to prevent.
