I partially agree with you. At the next world cup in Canada, the USA and Mexico, we should not expect the restrictions that existed in Qatar, such as the ban on serving alcohol, but there are other possible restrictions and problems.
First of all, I mean the fact that it is very difficult for citizens of most countries in the world to get a visa to visit America.
Considering that most of the fans are young people, usually unemployed, this could become a serious problem.
In addition, America as a country is very expensive for tourists and the question is how many fans will be able to afford to visit America during the soccer world cup.
the other disadvantage is that not everyone will be able to get US visa and most of the people will be planning to go there and would never come back.
Qatar on the other hand is a different country - it is secure and have a flexible visa policy and now none would be in hiding there.
