they should be built/deployed at a capacity as its needed in order of minimizing waste
Building at capacity might not be the most efficient solution. First, towns grow. Second, China keeps costs down by standardisation (the Chinese HSR system has, if I remember correctly, 3 models of trains and two standards of track). And third, China is vulnerable to earthquakes and floods. So having alternative routes is useful.
The issue specifically is that there is no population centres in which these unprofitable lines run through
And no, government don’t and should burn thousands billions; and hundreds of millions in upkeep every year because what if maybe urbanization stops and people for whatever reason move back to the countryside
