If we go out to work again while not having some degree of appropriate fear about catching the virus, we won't be careful enough, people won't bother washing their hands, and cases will shoot up again. Reassuring people that catching the virus is no big deal is not helpful (that was the dominant message back in February, after all).
We need to stay appropriately and usefully afraid of catching or spreading the virus, so we are careful, and do things in as safe a way as possible. However, we also need not to be afraid of going out to work and life again. How to resolve that? We resolve it by working incredibly hard, collectively, to keep the number of cases of coronavirus as low as possible. This is where testing, contact tracing, quarantining, social distancing and so on come in. This is where we all have a part to play and can collectively make a huge difference.
Unhelpful (and untrue) reassurance: telling people "catching the virus is no big deal, don't worry". Unhelpful because it will lead to more infections again (very bad for the economy as well as health) and untrue because it clearly is a big deal, it's clearly not just a cold for lots of people, and it's quite rational not to want to be ill (potentially for weeks) even if you're not that likely to die.
Helpful reassurance: being able to tell people: "this is a dangerous virus, but cases in your local area are currently low and we’re tracing them so you’ll have some warning if they start to go up". Then people can know going out is relatively safe before they do. But then when they do go to work, they still have an appropriate level of caution about actually catching the virus (because it’s a scary virus, and the risk will be low but not zero), so they'll carry on being careful about hand hygiene, social distancing, letting employees wfh - all the things that we need so we can keep cases low.
There's no quick fix - even if you could magically persuade everyone not to care about catching the virus, all the would happen alongside their newfound confidence about going to work is that precautions would be abandoned and cases would shoot up - which also fucks up the economy. Telling people just to get real and get out there is not going to solve this problem.
