No but you can see this easily yourself if you look at the theoretical limits and the formula involved.
Transmission of energy is E=MC^2. Using laser beams you could precisely target something to send the energy to.
accelerating mass would require you to use (kin)E=1/2MV^2 twice. One for bringing it up to speed and one for slowing it down. Propulsion of mass would require you to pack that (kin)E on top of the mass while the transmission only needs you to convert the mass to energy. Which theoretically only loses some negligible amount of energy.
Let's say we want to send M=10,000 kg of cargo to a colony 0.1 lightyears away. Using the transmission method this would result in
Assuming 99.99% efficiency (would probably be higher but it's the rate you gave) this would waste ~9*10^16 Joules
Transporting the cargo at a reasonable time to reach it (3 months) requires 30% the speed of light. Fusion propulsion could have acceleration of v=700km/s=700,000 meters per second
2,5*10^16 Joules times 2 (also for slowdown)= 5*10^16 Joules which is very close to the cost of transmission. Only the difference is that the transmission cost stays the same at higher distances and moves at the speed of light.
if the efficiency is just 1 order of magnitude bigger in reality cargo transport would be complete nonviable.
Fuck after having written this all out and reading your post I see that you're talking about the solar system's astroid belts of which the kuiper belt only has a diameter of 0.00006 light years and therefor conventional cargo WOULD be more efficient.
It's still ridiculous that interstellar trade will be faster than local trade due to this though.
