I would say the best way to explain it is that it is because the fortunes of a franchise can oftentimes be affected by things outside of the control of a team's FO, or coaching staff, or roster; such as injuries, off-the-court issues whether it be criminal or familial, free agents from your team leaving for personal reasons (i.e. Kawhi), etc. and so by nature it is not purely meritocratic. To balance the intrinsically chance/luck-oriented nature of an 82-game season, the playoffs, and free agency, it serves the NBA best to give teams the perform the worst the best odds at the highest picks. 
So let's say the Bucks flame out the next two years even though they went all in with Jrue Holiday and Giannis demands a trade. The Bucks' record craters - it's not that the Bucks didn't try their best, but now they are terrible, so to balance the personal decisions of individual players the high picks are the compensatory system. The NBA is largely meritocratic but not entirely.
