I get what you're trying to say but having multiple potential buyers is literally the definition of liquidity. If you only have one for what you're trying to sell then it's very easy for someone else to sell their share and boom you can't get rid of yours. These secondary markets work because there's a low amount of buyers AND sellers but if there would happen to be a sudden surge in sellers then the low liquidity of the market would eventually show itself.
