LEO means low latency which means real time guidance among other capabilities. All the support to the warfighter will get better, faster (to deploy), cheaper AND longer-lived.
Your replies again tell me you have no concept of what a national system to support the warfighter includes and how it has to work 24/7/365 and the complexities of getting vital data from sensors to cockpits (as one of many examples). It cant ever go down, be out of service, and must supply products that you cant get through COTS. It has to be robust to all sorts of attack and it has to be secure from hacking. You can wish for something that ain’t if you want, but the reality remains.
I will give you an unclassified example so you might understand better.
GPS. To maintain GPS service world wide 24/7/365 with the accuracy required by the warfighter to ensure the when we drop bombs they land exactly on target and not 50 feet away where there might be our own soldiers, we have to build and fly 30+ satellites in the high radiation environment of MEO. Those satellite have to have rubidium or cesium atomic clocks that must keep time to nanoseconds. Clocks like that cost millions just by themselves, forget everything else on the satellite. And you have to carry multiple clocks in case one starts going out of spec. The satellites take years to build and test. The testing is more expensive that the building, but we test so we don’t spend 100 million dollars to launch something just to have it fail on orbit. Follow the satellite with a worldwide ground network so you can track performance and upload the tracking data to the spacecraft at least once each day no matter where its at, all secure from attack or hacking. Follow this with systems on the ground to monitor and correct issues in near real time. Before you get done accounting for all this, you have a small marching army with one mission in mind...to make sure that we can drop a bomb anywhere in the world at any time from 40,000 ft and know that it an go down a designated chimney of one house and not damage the house next door. You don’t get this capability cheap.
Your replies have you focused on the cost of a satellite. You have to refocus on what it takes to make the mission successful.
