By 'people' making their own decisions, you mean 'employers' right? Because that's how it'd pan out if it the government didn't otherwise mandate it. And of course, we can always count on HK employers having the safety of their employees at heart.
I'm the only one in the office here in Central. I walked over during a quiet spell, but looking outside at the current buffeting winds and rain, I think it's completely reasonable that employers be told to keep their staff from going in to the office. People who *do* want to come into work, will.
As an aside, I spent last night hiking in the T3 over the Dragons Back. That was pretty exciting- I did get knocked over a couple of times
