If Gilgamesh messes around long enough I see him hetting his consciousness/soul removed from his body, leaving his empty body along with his treasury behind in the real world. Resistance is not immunity after all, so that's also a fair point.
Unless we're talking about the "mortal" Gilgamesh in Fate/stay night, then as a Servant his "body" is merely a glorified hologram made of magical energy and spiritual particles that closely mimics a living body, but is more accurately described as
incomplete materialization of the soul itself. The class of a Servant serves as a vessel that prepares them for their role as a familiar in advance, allows them to take on that role to help them take form, and brings them forth into the world.
More importantly, the class vessel acts as a limiter—Heroic Spirits are the most powerful of beings with which even the five magicians would never be able to forge a contract with—so each class identifies only the core skills of the Heroic Spirit, because replication of all their abilities using magecraft is impossible. If Road's power removes the soul from Gilgamesh's "body" (the vessel that is his Servant class... although it still shouldn't matter even if we're talking about Fate/stay night Gilgamesh, since his physical body serves just as well as a class vessel for a limiter), does that mean what manifested in her Dream World would be the true Heroic Spirit Gilgamesh? Because if that's the case... good job Road, you upgraded your opponent to his vastly superior 5-A+ MFTL+ form and ****** yourself in the process. I'm not sure everyone else would interpret her power working this way, though.

That might be true of most characters, but that would not be the case for Heroic Spirits. Noble Phantasms are not physical items that exist in the "real world" (save for some very rare exceptions like
Avalo that still physically exist in the real world), but rather
they make up part of the existence of Heroic Spirits, the anecdotes about their prowess and weaponry all becoming part of the very "symbol" of their existence. Since Noble Phantasms are part of a Heroic Spirit's very existence, and seeing as how Heroic Spirits are spirits, Noble Phantasms can be considered a part of a Heroic Spirit's spiritual identity—part of their soul. Unless Road possesses some hefty soul manipulation (it doesn't appear she has anything more than "soul removal") then pulling his soul into the dream world should logically also mean pulling all of his Noble Phantasms in too. The Gate of Babylon, while once a physical treasury, has ascended to the
embodiment of an endless treasury containing all the world's riches, rather than an actual location in spacetime that contains all the world's riches.
As anything can be found within the vault, the amount of wealth within exceeds even Gilgamesh's own knowledge; it is said that its inventory of treasure continues to increase even now. Noble Phantasms like Gate of Babylon are the embodiments of the legends attributed to Heroic Spirits, forming important parts of their spiritual identity, and are thus practically inseparable from them.
