The problem with pillar #3 is that it would likely lead to especially talented high schools players being able to force their way to the destination of their choosing. Let’s say the Sixers and Lakers are 1–2 in the draft order, as they are slated to finish right now. Crazy Talented High School Player X could basically say, “Philly you better not draft me, because I’d rather play in Los Angeles. If you pick me, I won’t even meet with you — I’m going to college.” Unless I’m misunderstanding your argument, this is a trump card that none of the college players would be able to play, which isn’t really fair to them. We saw this kind of thing get abused in the baseball draft with JD Drew, who refused to play for, ironically, the Phillies and went back into the draft the next year, and it was ultimately harmful to both the players and the teams.

Now, you can also make the argument that a player should have the right to choose where they want to play, which I think is a fair argument. But if you make that argument, you are basically advocating to abolish the draft altogether. And a league with no draft is undoubtedly going to have competitive balance issues.
