When I argue with people, I use the term "lockdown" to exclusively mean government-imposed lockdowns. After we've witnessed the experience of northern Italy in February / March 2020, most informed/reasonable people concluded that the situation is more serious than previously indicated, so it's obvious that people's habits would change. People are somewhat rational, after all. But arguably self-imposed/-chosen changes in human behaviour can both better account for individual differences (in health, exposure, and risk aversion) as well as respond much faster to short-term, local changes of the situation, compared to government policy.
