Switching flags to chase a better shot erodes fairness and national identity. Talent should be cultivated in a country's system, not bought by passports.
True gentlemen grow where they are planted; chasing another flag harms the root of fairness and breaks the covenant with their people.
Like variation seeking a fitter niche, players switching nations can adapt and lift the game's quality. Fairness comes from clear rules, not from banning ambition.
