For the 32-tooth cog that comes on a Trek Verve 2, it's like gaining about 5 teeth and becoming a ~37T cog.
I understand what you are saying, but when you look at gear inches the ratios just aren't that big. Even changing to a 40t cassette is only 4.8gear inches. That might be worth it, but a new cassette, chain and possible extender will also be in the $50-$100 range. If the guy said he had a 80's road bike with a 53/39 and a 13-21 cassette it would be a different story
IMO getting 3-4 gear inches isn't enough to spend $50 - $100 when his fitness will most likely increase to make it a moot point in a couple of weeks.
