Never talk in absolutes.
Should someone who does not know the risks of paper wallets use them? Probably not.
Should someone who knows how to make them secure, understands the risks & vulnerabilities and such use them if they want to? 100% yes.

People in general have gotten used to banks / brokerage houses / and so on keeping their money somewhat safe. Now that we have to take some responsibility to keep our funds safe there will always be "a better way to do it" but everyone will do what works for them, not what is "better" since what works for me might not work for you.

Also, keep in mind you still see how at times the failures of this. There are news items popping up about how people bought an old house and while renovating it found cash / gold / other expensive items in the walls. At times the home had passed thought several owners before it was found. Guess that secure method did not work out well for the person who did it.....
