This is a good argument; that everybody can play because you just need a referee and not a lot of extra judging help or technical stuff. This is a good explanation of why soccer is so popular. The other one is that unless other sports you just need some sort of ball to start playing. Actually we played 5 to a side (smaller field) football/soccer in college without referee and without the offside rule (which would make it hard to call). The only point of friction between teams were the faults (only obvious ones were called) so it could get a little rough but other than that the situations are mostly obvious and you can do without a ref in friendly games. For critical decisions in a World Cup soccer could use video replay though, especially since the scoring is usually so low (average is about 1.5 goals per game so far I think) that a goal changes everything. Perhaps it could be used after the games just to punish "divers".
