Are we not taking the club at its word that it's just for anti-coronavirus measures? If and when fans are allowed back, I expect it'll be about 25% capacity, so crowds taking ages to get in aren't going to be a problem. Anybody hoping for a decent track and trace system as part of the plan to defeat the virus is going to have to get used to measures like this.
People rightly say the response to the coronavirus has been shit, but then get all angsty when some mild infringement of perceived liberties is involved. In South Korea, they track people's credit card spending to see where they've been if they test positive.
