Considering how hard it is to make the Olympics to begin with, we're talking.... At any Olympic games, maybe 300 athletes in the entire country actually make the Olympic games. We're talking about a very small number of people to begin with.
When we're talking about shooting sports, to be able to produce an Olympian you need a huge mass of people competing to push each other to do better and to strive for better achievements and performances. If you cut off access to the competition, the training and the teammates, you essentially obliterate any opportunity we have of putting an Olympian into the Olympics, let alone onto the podium.
You need the opportunity, the training and the availability.
