Season flu has a typical death rate of 0.1%. The reason it "kills more people" is tens of millions are infected each year.
Coronavirus death and intensive care admission rates are much, much higher.
Slowing the rate of transmission makes a significant difference and isn't futile effort. If medical systems are overwhelmed by too many all getting sick at the same time, those requiring hospitalisation/intensive care will not receive the care they need, and the death rate would be higher.
At this stage containment is unlikely. The best case scenario is trickling a manageable number of critically ill patients through the system, minimizing casualties, and hoping for natural viral mutation/vaccines/weather influences.
