I am just talking facts rather than opinion (the reason the last line says "I am confident that no one is likely to find a different construction method that will be as light or for anywhere close to the same cost.......")
It is a viable and likely optimal way to do it if weight and cost are important engineering goals.
If those aren't goals (in an airplane like the RV-12 the first one is a very high priority), there are a lot of other ways a tank could be produced.
