Reasonable point. To clarify terms, what Livermore calls "ignition" measures the input energy as the laser energy delivered onto the target, not the power used to generate the laser pulse, which is what would count in operating a power plant. What makes ignition significant is that it marks the threshold where the energy generates starts increasing faster than the energy delivered, so there's hope that if we could make a laser that could deliver higher energy it could produce a lot more power. However, it took over a decade to build and start running the National Ignition Facility and another decade to improve its performance to reach ignition. The NIF design is over a quarter of a century old, and the laser technology has improved a lot, but we need to scale up the laser design and build a new generation of laser, and that's going to take time to get up and running. We're still much better off than we were in the late 2010s, when most observers thought NIF would never reach ignition.
