"unfathomable money issue"
how many billions have Japanese government spent on building stuff? How many billions of tv/streaming advertising slots have been booked? does IOC want to refund the billions in broadcasting rights they've sold?
"despite Scott Morrison's travel ban"
there is no ban. Just a Level 4 advice not to travel.
" If this gets into 3rd world countries"
USA is in deep trouble. They're pretty much toast. Their reported numbers have more than quadrupled this week and we know that's greatly under reported - they've only just established their testing regime, and it's 8 weeks since that first case in Seattle. Their slow response means they've now even got cases in their island territories - Guam, Puerto Rico and US Virgin Islands. They also have a culture of strong resistance to efforts to curb individual freedoms, like personal movement. So I expect their numbers to be in the million plus range by July 24, when the Olympics is scheduled to start.
Most of Australia's cases linked to overseas travel from known destinations have been attributed to travel from the USA. We were similarly slow to respond with self-isolation and entry bans from USA entrants and entrants from elsewhere.
And if the Olympics go ahead, will athletes and officials be expected to stay in the Olympic Village to reduce risk of COVID-19 getting into the village and infecting everyone? Or will the village become a hotbed of infection anyway, like the Diamond Princess, because there's bound to be some athletes and officials who bring COVID-19 with them?
