Wrong. Wheels have absolutely no relation to gear ratio.
Tire diameter effects gear ratio, but you can choose tires for larger wheels that have an equal tire diameter as stock 17, 18, or 19's in 20" sizes without affecting gear ratio.
That being said, if you choose tires with different diameter than stock, say approx. 3/4" shorter or taller, the effect on gear ratio is minimal, about 3% on average. At 70mph you'r speedometer would be about +2mph with smaller tires or -2mph with larger tires.

You don't lose power if the overall weight of your 20" wheels/tires are the same overall weight as the stock 18" or 19" wheels/tires, which isn't too hard since the factory wheels are usually on the heavier side.

Agreed, the right 18" wheels can look nice, but you need to know what your plans are for the brakes, as more of the 18" wheel choices will
not work with the larger 14" Brembo brakes, or other big brake kits.

The Corvette has done this since the C5 in 1997. Other car high performance car manufacturers do this as well, so apparently there is real benefit when tuned and setup. Just because it doesn't make sense doesn't mean we should fear it.
