They would have had to increase the number of troops to stay any longer, that's the answer to your question about why they didn't. Ramping up the war again after years of promising to end it was not worth it in any sense politically or militarily. The military industrial complex can be fed while doing something that at least has a chance of achieving other national interests, as in Ukraine or Taiwan or whatever.
The war in Afghanistan was lost, the US failed to accomplish it's objectives and eventually quit while it was behind.
