No, the big issue is that people seem to think you need permission to "obey the laws of physics". I have no way of enforcing a license under legal regimes with which I can't negotiate. Therefore such terms are meaningless and useless for my licensing purposes. The MIT/BSD licenses require legal interpretation and are not appropriate. Even the "public domain" is a jurisdiction-defined term that is not universal.

How can I create unambigous legal language if I don't know the laws to which I am subject? Am I supposed to assume US or "Western" style copyright? Will this work in China? What about Russia or North Korea? Does this language work in 2122? 2222? Under what authority?

And since I live in the US, let's be clear: nothing will prevent someone from suing you. The best chance you have is to hope the judge agrees with your interpretation of the law.
