Once you leave the maxi mindset and open yourself to the messiness of life it becomes an easy problem solved by hedging. The only tool you need is called "trading". And we have created DEX and atomic swaps that will assist you in seamlessly going from BTC to XMR and back.
With 0.25% of your BTC stack you can fully hedge in XMR. It's a very small price to pay for the best privacy at the cost of "some" auditability.
Yin and Yang, BTC and XMR are like the black (private) and white (transparent) aspects that make live go round. One can not exist without the other for a longer time. It's all about different trade-offs and upsides/downsides and constant rebalancing. No life without frequency.
Maximalism is not compatible with life processes. Maximalism is an interesting theoretical concept, but it describes an unstable condition.
