If Bitcoin does not exist, then Bitcoin Cash does not exist.

Considering how Bitcoin Segwit does not fit the white paper or Satoshis explanations of the system design, I would tend to agree on this point. "Bitcoin" is Bitcoin Cash per that definition and as such either Bitcoin (Cash) exists or it does not.

The Bitcoin Cash Development Team cannot write their own code.

This is obviously not true. The Bitcoin Cash development is done by several teams, converging on particular things. They definitely know how to write code and there is no dependence on the old 'Core team's work on Bitcoin Core/Lightning and the Segwit chain.

I think the old format, style, type, address of Bitcoin Cash is better for Bitcoin Cash.

This is just a repetition. You still did not give me a reason why the old address style is better than the new, even as I'm being very open to such a point of view.
