and other incentives too - enforcement is going to be hard on the scale of "everyone on the planet", but I wonder why people who got the cough went back to work. Would it have hurt their employment prospects to take the time off? Did they have responsibilities that were not able to be covered by coworkers? Understanding why people don't follow the rules by themselves is important - tweaking the incentives in the system could help to lower the R rate, where I think having the police monitor the social lives of everyone on the planet is not a viable solution.
