Let's take this question two ways.
- Assuming Schnorr requires a hard-fork - let's take into consideration what that could do to bitcoin in context of this question.
- let's assume schnorr is deployed without major problem or impact to bitcoin (seems unlikely but would be very nice to see the community band together for something so fundamentally bitcoin as privacy). Does monero lose all it's advantage over bitcoin?
Sorry if this is too discussiony,trying to be more question oriented but the speculative nature of the question lends itself more to discussion.
