Sure. But it's nice to have options. Some approaches are more intuitively obvious to different people.

If you use energy, then you have to introduce mass and this is not necessary.

Mass disappears by cancellation. No biggie. Or use specific energyIf you use energy, then you have to introduce mass and this is not necessary.
