Really? I thought the opposite-- they certainly make the case against overly broad patents, but then say "If an inventor has a really original and outstanding idea, then a patent might be merited."
It's these "really original and outstanding" ideas that the patent system is designed for, and why "non-obviousness" is supposed to be a requirement for a successful patent application.

E.g. they do _not_ have deposit insurance (on bank deposits).
The biggest problem is moral hazard. With outside guarantees you don't care about default risk. And debtor will compete solely on return, not on risk-adjusted return.
Without an external backer, you will watch your bank much more closely. And banks can't be watched closely enough.
The Reserve Bank of New Zealand has a page (http://www.rbnz.govt.nz/finstab/banking/regulation/3256868.h...) explaining why they don't have deposit insurance in New Zealand.
