so he has a point, but to clarify.
Steering stabilizers are meant for one purpose and that is to dampen shock loading or unloading of the vehicle's natural reactions to road imperfections. they will help reduce wear and tear on other suspension components as well over time. however they will not correct incorrect steering or suspension setups.
They are most commonly used in SAS or SA rigs because of the notorious issues that plague a solid axle front end. people often try to use SS's to fix excessive bump steer incorrect steering geometry or death wobble. those issues are normally associated with anything from mismatched tire sizes, tread, pressure to bad suspension components or just flat-out misalignments like caster ect...
In short an IFS rig can benefit from them but its usually minimal and just helps feel. there are cases where they can help with oversized tires more so.
