Scenario
Team A sells older vet
Team b has been running at salary floor, losing getting #1 draft picks training selling etc.
Team b buys team as vet at a market estimate high or barely higher price, no harm to them they have the money. Team A gets more than their player may be worth. Repeat process infinitely.
Further compounded by smaller nations, less leagues, less leagues turns to make tons of money quicker...
No even with the best of intentions this is a flawed plan and could too too very easily be abused
