Because it takes 3 hours to get it apart far enough to even see the jack.
3 hours of shop labor at $85 per will run an appreciable fraction of a new laptop


I do power jack repairs and replacements quite regularly. For
example:

The time it takes is usually a function of how much damage was done to
the PCB, whether I have the correct jack in stock, and whether I need
to remove the motherboard to replace the jack. For power jacks with
connectorized pigtails (some HP and Compaq), I can be in and out in
about 45 minutes. For laptops with a zillion screws securing the
motherboard, about 2 hrs. Shop rate is $75/hr and I typically quote
$80 to $160 for the job, which includes cleaning out the crud, fan
lube, keyboard cleaning, and quicky charger/charging test.
Incidentally, I find a substantial number of bad power supply cords
and connectors, so don't assume that it's the jack without first
trying a different power supply.

Hint: Take a photo of the PCB, print it, put it over a sheet of
styrofoam, and shove the screws through the page in their original
locations. That way, you don't forget to reinstall any screws or put
the wrong length screw in the wrong hole.

As for "an appreciable fraction of a new laptop", I'm curious as to
what percentage of the cost of a new laptop you would be willing to
pay for a repair?
