[General] Why are space fighters not used in the expanse?

Wouldn’t fighters have a higher chance of survival if one missile can incapacitate a large ship like the donnager during its battle with stealth frigates?

The only logical reasoning seems to be cost or human pilots holding back their capabilities.

One of two things happens with their tech: either A) you build a ship with all the resources to keep a single pilot alive and healthy on a long-haul between wherever the launch point is and where the target is, in which case you don't have a snubfighter you have a barchelor apartment in space or B) you put the fighter on a fully equipped mothership, in which case you'd be better off with a pilotless missile-armed drone, or the fighter's mass in missiles and PDG ammo, and you still haven't solved the vulnerability issue.

Building a decent space fighter in any setting where inertia is a Big Deal is basically a non-starter, since there's not a lot of fancy maneuvering that can be done without crushing the pilot. And without the ability to dodge, survivability comes in the form of armor, defensive guns, and enough internal space for a rail slug to pass through without killing the whole crew, all of which a one-person craft would lack.
