There certainly is a reason orthodox Judaism can't adopt that principle, it's a compromise with the world which is enmity with God. The Torah is the standard and it says God was angry with Moses for his failure to have his sons circumcised.
Satan often acts as God's agent in judgment, and in any case he can't act without God's permission.
When God is your authority and His law is contradicted by human law, the offense is on a very different level from personal offense. And this is all very similar, you know, to the dilemma Christians have been put in by the legal adoption of gay marriage. Genuine devotion to the biblical God requires us to disobey the conflicting law, and I'm figuring the same is true for orthodox Jews in the same position with respect to the biblical requirement of infant circumcision. These are things you can't dictate as an unbeliever. Many Jews may capitulate to a secular law against circumcision, as do many Christians to the gay marriage law, but strict believers will not do that. Strict believers do not see their religion as evolving, the more the society directly contradicts God's word the more we are put in a difficult position because we won't give in to the changes. It's God's word, after all, which is not humanly alterable. Sure you'll see a rise in apologetics in favor of any compromise that gains popularity, but it's at heart a giving in to alien influences at enmity with God, a betrayal. Perhaps it's a way of separating the sheep from the goats.
Yes many things that had a basis in the Bible have been changed by the societies we live in. The death penalty is one, and I think we're under judgment for that among other ways we've compromised God's word. "God is not mocked." There are consequences to rejecting His instruction, which of course unbelievers don't register. If an earthquake or a hurricane or a drought or an increase in social violence or the ingress of hostile foreigners or an economic crash (all on the Biblical list of punishments for disobedience to God) makes life miserable for a populaton they don't notice the connection.
