For FIFA World Cup 2022 Qatar venues, there are 8 stadiums in total, and for each stadium, there will be 7-10 matches in total.
“Eight stadiums will host matches at the tournament, seven being newly built and one being refurbished.” (via: The Most Expensive World Cup Ever »)
Surely, there can be other events, but to consider building a stadium for 10 matches so that the whole planet can watch some football games looks like a poor allocation of resources.
A solution? Make the World Cup last longer and reuse some stadiums.
Another solution? Run some matches at other times than when the whole world is watching.
The big problems are with the group stage matches, and solutions can be found.
But, of course, you could also build 7 stadiums, so no one gets upset (this was sarcasm).
