how ridiculous does that sound.
Depending on what you're talking about, not very. Context.
You're not making a very meaningful argument here, just mocking someone's clearly-stated and coherent semantics.
It's the same when you compare it with using 50% of your energy while riding a bike. On a normal bike you might do 15 ~ 20kmph doing so but on a racing bike (skinny wheels and more aerodynamic seating position resulting in less drag) you will go much faster using the same amount of energy (better optimization).
"Skinny wheels" actually has fairly little direct benefit to bicycle performance.
There are two major factors to tire rolling resistance:
1-As tires roll along the ground, energy is lost as they deform and rebound. Wider tires "deform" less for a given amount of vertical deflection, so if a wide and a narrow tire are set to be about equally squishy, the wider tire actually does better in this regard.
2-Suspension. When a tire rolls over surface irregularities, it can deform around them and behave as suspension for the rest of the bike, or it can propagate the deflection upward to the rest of the bicycle (and deflecting a bicycle upward over irregularities is a big waste of energy). The squishier the tire, the better it tends to perform as suspension.
Since wider tires can do (1) as well as narrower tires when squishier, rolling resistance tends to be overall
more favorable for them, assuming a wide and a narrow tire are otherwise constructed similarly. (On the other hand, width tends to make tires heavier and less aerodynamic. These counterbalancing effects mean that - within something vaguely resembling reason - tire width tends to have relatively little direct effect on paved performance, much less than other aspects of a tire's construction.)
There are two main issues holding back the performance of wide road tires, and neither are a direct result of them being wide:
1-There are very few tire brands that actually make high-performance road tires in wide sizes. The vast majority of wide tires are either MTB tires, or are sluggish bombproof rubber bricks intended for long wear life and puncture-free touring or whatever.
2-Aero road racing rims are designed to form an aerodynamic shape
when a tire of specific width is mounted on them, and they don't make such rims for tires more than 30mm wide.
The good news is that, in recent years, high-performance wide road tires are becoming slightly available. Road-ish bikes equipped with super-wide tires are a blast: they can be pretty comparable to a "normal" road bike on pavement, while still being perfectly happy to veer off onto gnarly gravel roads.
