What is wrong with a strict moral code?
This is an awfully vague question.
Nothing is inherently wrong with a moral code, the question is qualitative: what type of moral code? Where does it come from? How is it enacted?
The issue with a 'strict' moral code is that this rigid line is usually drawn by some individual(s) distinct from the individual engaging in moral action (ex: the church declaring what is right or wrong). This is an extreme form of authoritative oppression, as the individual in question is not licensed to dictate his/her own moral feelings, and must conform to those of the authority. This, in turn, further consolidates political power (political power drawn from moral authority) towards that small group of people dictating moral codes. Consolidated political power always leads to abuse.

If we have no business with the construction of the future or with organizing it for all time, there can still be no doubt about the task confronting us at present: the ruthless criticism of the existing order, ruthless in that it will shrink neither from its own discoveries, nor from conflict with the powers that be.
