In the process of trying they'll very likely end up with a set of contradictory and/or impossibly ambiguous rules. They'll also encourage people to think that by compliance with the rules they've done all they need to. They'll encourage still others to abuse the rules in ways detrimental to other people. And they'll discourage a lot of harmless and possibly useful / interesting / fun discussion out of fear that it will be interpreted as a violation.
Gender bias and stereotyping are problems of culture. The various violations are all questions of judgment. Those judgments will always depend on questions of context. That doesn't mean the problems are unimportant or that there can't be consensus judgments of a full set of facts. But it does mean you cannot solve questions of integrity and intent and interpretation with external rules.
