Demurrage makes protocols like Lightning much more complex, and isn't
compatible with existing implementations. While demurrage could in theory be
implemented in a soft-fork by forcing txs to contain an output with the
demurrage-taxed amount, spending to a pool of future mining fees, I really
don't think it's practical to actually do that.

Anyway, demurrage and inflation have identical economic properties. They're
both a tax on savings. The only difference is the way that tax is implemented.
