It can be quite easy depending on the laws of the world, but when it comes to Avalon in FSN, it’s a bit different. In this case, its shape was changed from a physical object in the form of a sheath, into something that flows within the body. “Destroying it” is simply erasing the possibility from it ever being used or reformed again. Rather than being destroyed, it seizes to exist. You need all pieces to complete the puzzle, right? So since Shirou’s body was destroyed, it probably couldn’t be fully extracted by anyone even if they knew about it.

She probably would attribute his healing to Archer’s arm. His physical as well as magical capabilities increased after all. Before that, I don’t remember Shirou getting any larger wounds that would heal quickly.
Besides, Avalon’s healing largely diminished after he lost Saber. It might have gotten more active after Shirou got Archer’s arm, because it got some sort of supply of greater magical energy. It was an alien thing that was slowly killing Shirou though, so Avalon might have tried to purge it from his body. In the beginning this effect could be restrained, but after the power of the arm was released, it was no longer possible.
That way Avalon would have started having the opposite effect to healing, leading to swords coming out of Shirou’s body wherever he was wounded in the final scenes of HF. Perhaps Archer’s strength was used to withstand the strikes from Kotomine, while Avalon denied Archer’s influence and replaced it with swords.
I think that without Avalon, Archer's arm would destroy Shirou's mind rather than his body. That way Avalon would be killing Shirou's body by denying Archer's arm that was trying to kill his mind.

The sheath might be called Avalon, not because it is the physical form of a paradise world Avalon, but because it provides the effect of "not being disturbed by anything". The title "The All Distant Utopia" might refer to being impossible to reach. Gilgamesh called it "The Ultimate Defense" in Fate Route. He said what the world Avalon is, and described what the sheath does. I don't think the line meant that the sheath was the world.
It's just a sheath and not a Reality Marble like Unlimited Blade Works, so personally I don't consider this sheath to be the world Avalon, nor something linking to it. King Arthur was supposedly taken to Avalon after his death, but he didn’t have the sheath at the time, right? Sure, Saber might have gotten it from Shirou, returned with it to her timeline and died with it, but I don’t think she would go to Avalon using the sheath. It's just her spirit that would be taken there.

The world Avalon might transcend time and space like the Throne of Heroes, but not the sheath Avalon. If it actually worked like the galaxy thing from "Men In Black", then all the different timelines would have different Avalon worlds.
If the sheath actually IS the world Avalon, then perhaps the sheath is the physical form of the paradise in the human world and doesn't have any influence on the paradise within the sheath.
Personally, I'd rather say that the sheath Avalon and the world Avalon are different things in FSN.
