While a cypherpunk myself; and a fan of fully trusted setups, generating seeds with own entropy and stuff like that, I think Andreas is speaking to the 99% of the crowd who probably aren't even on this forum and would 9 times out of 10 mess up a paper wallet.
If you know what you are doing and you use a setup like Loyce (with dedicated offline printer and computer) and such, go for it - there will be less trust involved.
But the majority of people will create a paper wallet probably with the online version of a
potentially malicious site and screenshot the seed; thus making it heaps more secure for them to just use a hardware wallet.
