Therefore, movement restrictions should be a last-resort option not to be endlessly deployed in a multi-year pandemic. There are several reasons for this. Restricting human freedoms is morally, legally, administratively and economically costly, no matter its short-term benefits in reducing cases. Restricting freedoms also attracts a lot of public scrutiny and risks a slippery slope to authoritarianism. Therefore, it is a strategy with rapidly diminishing returns and progressive costs to the government. This is supported by public health theory, in which there is a difference between human activities - such as exercising, shopping, socialising and travelling - and human behaviours - physical distancing, wearing masks and regular handwashing.
