From a physics perspective that statement
1) Makes absolutely no no sense. "Power generation" is not a thing. Power is a measurement of work over time.
2) Is patently incorrect. "Force" is the product of "speed" and mass, so increasing either will increase the amount of energy carried/transferred by a force. You're basically saying that in the equation 6 = 2 x 3 that the 2 is more important than the 3. Like... how?

Kinetic Energy = 1/2 x Mass x Velocity^2
Again, ^2 means that velocity is squared, which means that as velocity increases, it has a much greater impact on the kinetic energy of an object than mass does. This means that if you triple or quadruple the speed of a moving object, the power of a collision will have a much greater effect than if you triple or quadruple the mass.
Kinetic energy means movement and the equation is about movement. Comparing with an equation as 6 = 2 x 3 is just silly and means that you for some reason can't understand, don't want to understand, or that you are trolling.
In the equation 6 = 2 x 3, 2 is NOT more important than the 3. But if change the equation from 2 x 3 to 4 x 12, then the 3 has changed more than the 2. 4 is the double amount of 2. 12 is 4 times the amount of 3. 4 x 12 is 48. So changing 3 to 12 increases the total sum more than changing 2 to 4.
I sincerely don't understand why you have a problem with a simple equation that proves that the increase of velocity will have a more impact on increasing strength than the increase of mass. Maybe you complicate things too much.
From the perspective of a human body, muscles only fire at the rate they fire. There is a hard limit on how fast muscles can make you move. Once you reach that, the only ways to increase energy output are to recruit more mass or increase mechanical advantage.
Well, there's a limit to how much mass you can put on your body.
But most people can increase the speed of their movements better and faster than they can put on weight or increase the size of their muscles.

Most people look at the wrong end of the equation. The relevant acceleration (whether in F=MA or KE=1/2MV^2) is the negative acceleration on impact. The more solid and efficient one's structure is at the moment of impact, the more energy will be transferred and, hence, more damage done. "Leaking" power is a much bigger issue than an inability to generate power.
Exactly!
That is why I said that I rather speak about
supporting a striking fist with mass, than
moving mass to strike with.
The acceleration/speed/velocity is the first thing that is important.
Your structure/balance/support when your fist lands on the target.
It's harder to train to increase mass than to practice speed. Regardless what method you prefer, the body must give the fist a firm support. Even if you walk/run or fall into the punch, angles and timing must be correct to give the punch maximum support.
