What are you talking about? It has everything to do with discarding his ideal. Shirou's world and Archer's world are the same, it's called Unlimited Blade Works. There's a few cosmetic changes because their personality is different because of their life experience, but it's still the same world.
HF shirou is a completely different matter and the route beats you over the face with that fact.
That is not how Reality Marbles work. Once you have one, it does not just go away. Plus, Shirou is stated to be able to use one in the HF True epilogue.
I mean, Archer
himself has given up on the ideal, so if anything he'd be
closer to HF Shirou than to UBW Shirou.
I mean, did you zap all those arguments and soul searching Shirou goes through the night where he has to decide whether to kill Sakura or not? Archer says it plainly.
No, I didn't. But, given that his ideal is "save everyone", killing Sakura when she has (to his knowledge) done
nothing wrong and is not an
immediate danger clearly goes against that.
That's what it is about, to stop trying to save everyone and to decides to save a single person. He spends a long time agonizing over that dilemma until Illya tells him simply that "she'll always be on Shirou's side because she loves him" and that sets him free. He discards his old resolve in favor of a new one, and not something as light as "I'll save that poor, poor innocent girl" but "I'll save Matou Sakura, the girl I love, no matter what!" Morals and righteousness has nothing to do with it, he just loves Sakura and decide to stand by her side.
Whilst that is true, given what he knew at that point in time the correct way to follow his ideal was
still to try to save Sakura. Plus, at that point he makes the decision that, if she goes mad, he'll ensure that he kills her before she kills anyone else. So, he clearly still cared about saving everyone.
Later on, he becomes more firmly in favour of saving Sakura regardless (particularly when he makes the second decision), but even then he
still wants to save the rest of the world as well. So, whilst he claims to have discarded his ideal, honestly he hasn't really. He's just shifted the emphasis towards saving Sakura over others. He still wants to save as many people as he can.
But, anyway, this is irrelevant, because none of what you've said proves any kind of connection between discarding his ideals and not being able to use Archer's UBW.

Nope, UBW is born of Shirou's single-minded devotion to his ideal.
Reality Marbles do not work that way.
We see its birth during the Shirou vs Gilgamesh fight, when Shirou comes to term with how hollow and impossible his ideal is and decides to follow it to the bitter end anyway.
No, we don't. Shirou already
had his Reality Marble, he just didn't know how to
use it.
Liam-don said:
Fate Shirou traces by imagining the weapons in his mind. Before his fight with Gilgamesh, UBW Shirou did it the same way or copied the weapons his opponents used.
Which is an application of UBW. The
reason Shirou can copy swords that he has seen is because they're stored in UBW.
The only Shirous who use UBW for tracing are the ones... who have access to UBW.
So, all of them, then?
Seriously, Rin states in the HF True epilogue that Shirou could use his Reality Marble if he trained himself. You can't get much clearer than that....

Perhaps I should say that I feel the Heaven's Feel Shirou wasn't able to realize UBW as effectively as UBW route Shirou was because his ideals changed his UBW and the fact he had Archer's arm trying to impose its own UBW caused a conflict which limited its ability.
But UBW does not work that way. For one thing, Archer himself has
long discarded that ideal.

A: By reproducing stuff that are right in front of him or were contained in his body for a decade.
And, how does he do that in a way which normal magi could not?
A: Not doing the same way as everyone else because his incomplete training left it to focus only on that.
Incomplete training doesn't usually cause you to do something 20 times
better than someone who knows what they're doing....
Don't particularly care, as I'm only concerned with the single bolded sentence that isn't based on anything in the VN.
No, it's based on the Side Material books, which are
canon.
