By running a Monero node and typing in a command just like any Bitcoiner would do
A hidden inflation bug is potentially harder to suss out on Monero. But it gains the advantage of privacy and fungibility. I guess it depends what you think is more important for digital cash (nothing stops us from using both for different situations).
Technically it is true it is not verifiable in a simple manner, but in practice there is no difference in my opinion. Virtually no Bitcoiner manually makes sure every single input/output on-chain of literally over a billion+ transactions cancel out (and indefinitely every ten minutes on top of that).
They just run a node (if even that)
