Deserving

Many times when the rabbi talks about the naturalistic fallacy, he is referring to the problem of deriving facts from norms. On Wikipedia https://he.m.wikipedia.org/wiki/%D7%9B%D7%A9%D7%9C_%D7%A0%D7%98%D7%95%D7%A8%D7%9C%D7%99%D7%A1%D7%98%D7%99 I saw that this problem is defined differently – the problem of the present-is-appropriate. Does the rabbi disagree?
