It's a sector just like others which generates a feckload of money and job opportunities though, so in that regard it needs to be treated as every other sector, i.e. re-opening as soon as it's possible, or as soon as the risk becomes acceptable.
If you view it as "eleven men kicking a boll on a lawn for our amusement" then sure it's right down at the bottom of the list, but as a sector as a whole, it's just as important as others.
I'm not sure that all sectors carry equal importance (whether measured on economic output or overall societal good). That is not to say that football should be dismissed - the livelihoods of many ordinary people are undoubtedly dependent on getting football going again. Unfortunately, many millions of peoples' livelihoods are also dependent on finding a way to transition sectors like education, construction, retail and hospitality, back to something like normal operation. Sadly, some of them are likely to be heavily curtailed, at least until 2021 - this is just the harsh reality of the situation we find ourselves in. Whether or not football can be saved from the same fate that is likely to befall the bars and restaurants of this country, is too soon to say.
