It seems to me all of the powers which are responsible for the return of football in this country, namely the Premier League/EFL and the government, have vested interests beyond health which cannot be trusted. For the former, it's entirely financial, and for the latter, it's a distraction from the pig's ear they've made of the pandemic as a whole. Give the proles their circuses back and they'll stop asking awkward questions. It also has the added bonus of being a signifier come the next election: "remember, we got the football back in record time!"
Yes, it's a cynical way to look at it, but when they're discussing bastardising the game with non-contact set pieces and neutral festivals in closed grounds, it's hard to see it as a health issue.
