No. What we should be fighting against is the blacklisting nonsense. There are ways to protect yourself from trivial de-anonymization, even if the majority doesn't utilize them. The problem doesn't lie on privacy techniques, but on users who are confident with accepting arbitrary rules to pass from entities that don't want their good, and that rely on irrational mechanisms such as blacklisting every coin that comes from a mixer.

And we should fight for privacy protection, of course. The Lightning Network is a significant update to those who value privacy.
