Cost has nothing to do with it. This was all laid out in the project 2025 manifesto. Burn it all down with no regard to money previously invested. Makes it harder for future administrations to rebuild. Halting the collection of data is not enough. Maintenance is 5% or less of the cost to deploy new. If they destroy it, it makes the cost to rebuild (including having to re-seek congressional approval) that much harder and time consuming.
