The problem is that the cruisers are old and expensive to crew and operate, along with needing repairs and upgrades that the Navy is even more hard put to pay for. The Navy’s shipbuilding woes are partly of their own making, but Congressional meddling and stop and start funding have compounded the problem.
The decline of the industrial base is at the core. For ship construction, the civilian side effectively no longer exists and what remains is all dependent on military contracts.
Things got even more downsized for the Navy during the Mid-East Wars where the Navy role was minimal.
But here we are 20 years later, and China is now a Peer threat (and then some) and new capacity and even repair capacity is very limited.
