Here is a link to an excellent article on the buyout market which was never intended to exist. It needs to read in the entirety but below is an excerpt.

Some team executives have pushed for reform, to no avail. One suggestion is to make buyout players ineligible for the playoffs unless they have been released at some date before the trade deadline—say, in early February—thus incentivizing teams to trade for the players. Another option would be to create a compensation system, in which the team signing the player has to send a draft pick (or possibly multiple picks, depending on the player) to the player’s former team. A third proposal would be to give each team a cap exception specifically for buyout signings—and limit it to one per season, or even one every two years. A fourth option would be to have teams place a blind bid for bought-out players, using whatever cap room or cap exceptions they have available, with the player awarded to the highest bidder.
The small-market execs hope the issue gets addressed in the next CBA, which would begin in 2024, after the current deal expires. But they are not particularly optimistic. As they see it, NBA officials are driven by marketing and money, and having marquee names congregate in glamor markets, or on title contenders, is good for ratings.
“The way you know the NBA doesn’t think it’s a problem is they’re reticent to acknowledge it’s been a problem,” says one of the small-market execs. “The inaction tells you, ‘We’re cool with it.' "
