You mean cases in which people fail to pay a competitive fee.
Pony up 11 cents and you're golden.
For now. The trouble with the Bitcoin model is that if everyone takes this advice and ponies up 0.11 USD all cannot be golden because of the fixed supply. Price is not the issue here in fact it still likely costs more to send the funds via the Monero network.
The real issue here is the ability of the network to increase supply in response to an increase in price. This is basic economics.
