Well, its all relative.

What does he mean, better? How much better? 10%? 20%?

Clearly, there are other components which wear with use. Tires, bearings, transmission, engine, starter, just to name a few.

It sounds like he is suggesting you put from 2 to 4 times more miles on your car for any given time period than you currently do, which is going to wear out those parts, in general, 2 to 4 times faster.

Is there going to be that much more benefit from driving it every day for one hour, to offset the increased wear, not to mention your loss of time and cost of fuel?

In my opinion you are doing just fine.
