Hard lockdowns and aggressive contact tracing are incredibly effective when case numbers are very low. Contact tracing in particular becomes significantly less effective as case numbers climb. What they are hoping to accomplish with these measures is to stop the current outbreak in its tracks and return to low-to-zero daily case numbers. At some point they will fail to contain an outbreak (either intentionally or accidentally) and then the case numbers will skyrocket in a very short period of time.
