Absolutely.

If we were to hard-fork Bitcoin into BTC-private, I wouldn't assume that the fork can compete with Bitcoin as a SoV. The market price for Monero may give an indication of what the market is willing to pay for a 100% privacy coin.

And yes, Bitcoin does not need permission. Its protocol is designed in a way that it can become a global SoV.

It is doubtful if the market needs another Monero. It is clear that the market wants Bitcoin as it is.
