FCMP++ won't make XMR fees cheaper than Lightning - that's not the point. Lightning is a layer 2 solution that sacrifices some decentralization for speed/cost, while FCMP++ improves Monero's base layer privacy without compromising its core principles.

The real question is: do you want actual privacy with reasonable fees, or do you want to trust Lightning's custodial trade-offs? Most people claiming to care about Bitcoin's "digital cash" vision conveniently ignore that Lightning requires liquidity management and often custodial wallets for normies.

FCMP++ makes XMR's privacy bulletproof while keeping fees reasonable for base layer transactions. Different tools, different purposes.
