What doesn't make sense

Now it says that 33 countries need to be registered as "lacrosse playing" countries by the IOC ( International Olympic Committee). What doesn't  make sense about lacrosse not being in the olympics is that, lacrosse was played in the 1904 Summer Olympics, with only 3 teams, and later in the 1908 olympics with 2 teams. Today we have 23 countries playing the sport, if we could make it olympic with only three countries in the past, then we should be able to with 23 countries today. Plus if lacrosse were put in the olympics for only a year, then other countries would see it as a chance to win medals, causing it to spread and have more contestants for the next olympics.
