They need our money but most importantly is the government would benefit from that through tax collection.
That's the reason why they still allow the casino to open despite of the increasing number of cases as they want that money to help the economy survive.
Both physical and online casinos benefit owner and government. The owner wants the government to give permission to start the casino which will be adapted to health protocols as long as the pandemic still exist. The other party that benefit is the community, because many gambler are trapped during a pandemic so opening a physical casino will make them re-associate with others in the casino with new normal rules and habit.
Complying with health protocols is very important if someone is eager to go to a physical casino. During this online casino has given the freedom for gamblers to play anonymously and safely anywhere. The right choice if you want to prevent pandemic transmission is to play online.
