I'm struggling to find analogies here.

Everyone, you need to drive the Ford 35 Mustang. It's not the fastest car but it's pretty fast. If you strap a trailer on the back then sure it now loses all it's maneuverability but it's now a truck, right? So we don't need trucks any more.

Since it's invisible you don't need any combat capability, unless you load it out with 8 pylons and now it's not invisible any more, so now it does need to outfly the enemy. But it can't because it needs to carry all this load.

It needs to take off and land vertically which means it needs a small cross section but it needs to be able to have a high wing load to turn so it needs a large cross section.

It needs to do close air support but it can't get close. It needs to be slow but it also needs to be fast.

It needs to be a bomber and have long range, but needs to be a fighter and have high performance (or energy maneuverability).

It's what Boyd warned everyone about during the last generation, you need to avoid mutli role aircraft as they're not good at anything.

Like the F-16 or the F-15E? Hillaker said he'd have designed the F-16 differently(more akin to the F-16XL) if he had known it was going to be multi-role.

Right. It wasn't supposed to be multi-role, the original was a beautiful thing to behold before they started hanging all kinds of crap off of it.
Like radar?

Eh, if it went into production as they had envisioned, it would have been built only to F-104 kind of numbers. By compromising a little on the air to air aspect, they gained enormously in the air to ground aspect and overall utility. Most of the sorties have been air to ground for a good awhile now.

Have you ever thought about that it does not have to fulfill all those roles at once and that war is fought in phases which each require a different trade-off?
Yes.

These are the design constraints. Really it should be 2 or 3 different, almost certainly cheaper, aircraft.

beyond that if the guy in the ground need precise explosive delivery just build laser guided medium range rockets, a ship could bring thousand of those into any theatre with reasonable safety and skip the expensive delivery platform along with all the concerns for the meatbag inside
Laser guidance kits are pretty expensive which is why there’s a push to move to GPS guidance.
gps can't do the things the guy above asked for
