National debt doesn't work like consumer debt bud. Learn some economics. Nor is the trump admin actually using it to pay down the debt.
Anyway, defunding the NOAA to pay off the national debt is like skipping a coffee, once, to pay down a mortgage on a house.
This isn't exactly the type of work tons of astronomers are doing, nor does it cut into their jobs. Astronomers have already been using ML/algorithms/machine vision/similar stuff like this for this kind of work for years.
Besides, whenever a system identifies objects like this, they still need to be confirmed. This kind of thing just means telescope time is more efficient and it leaves more time for the kinds of projects that normally don't get much telescope time.
Also, space is big. 150k possible objects is NOTHING.
