If we trade for Simmons and get compensation, we theoretically have acquired the assets to dump him at any time or close to it. That could always change with the market, but going forward there are more teams with cap space meaning more teams willing to take him in a salary dump. But every year we have him, his negative value as a contract gets less even if he doesn't improve as a player. For example, we eat the cost next year, meaning we can't use the cap space....but the following year his contract is less negative and if we wanted to dump him it should take less value than what we got him for. We've gained value in that process, albeit at the loss of our cap space. If he actually improves as a player, we've obviously gained even more value. Cap space only matters if we use it, and we can always trade him if we need to use it.
