would be better to say
"summing the coinbase txs doesnt guarantee there hasnt been a undetected inflation bug. gettxsetoutinfo does."
because that explains what the "lesser" picture is.
but its not the whole story,
because we can manually verify that the txs on a block dont create new coins
and people do.
a la https://www.moneroinflation.com/
so.
while everyone makes decisions about what they're comfortable with
there's no reason to believe monero supply guarantees aren't totally solid.
