There is nothing wrong if you already have some old paper wallet, and you can use it just fine, but it's much better to have option for easy generating of new addresses, that is impossible to do on paper wallets.
With single key paper wallets, sure. With HD paper wallets, it's as easy as having a watch only wallet with your master public key on your computer.
However, which group do you think is bigger?
Clearly the group of those who do not have the technical knowledge required to safely set up and use a paper wallet far outnumber the group of those who do. But I agree that saying that no one should ever use a paper wallet because most people can't use it safely is wrong. Most people can't fly a plane safely or perform surgery safely - doesn't mean those things should be off limits for everyone.
They aren’t corrupt like the big banks and offer a .5% interest rate vs like .001% at Chase/Wells etc.
Off topic, but any interest rate below inflation means you are losing money. Whether you are losing 4.5% or 5% per year is pretty academical.
