A further point about the “slippery slope” argument. 
Vegas, smaller amusement parks, cinema, etc.  should all close.  Now.  Disney is a leader, the kind of leader Americans - and particularly American businesses - respect more then political leaders.  It is also, in a way only Apple might be able to match, a cultural leader.  Disney closing will be a huge push to every other venue to close NOW.  That’s another reason it has to happen right away.
It’s similliar to Tom Hanks getting the virus.  When Disney closes, low-info consumers and sluggish corporations begin to realize what is going on.
