If you assume the status quo - a powerful not quite human level AI - then you are most likely correct. However one of the primary winner takes all hypotheticals (and to be sure it remains nothing more than a wild hypothetical at this point) is achieving and managing to control proprietary ASI. Approximately, constructing something that vaguely resembles a god.
Being unfathomably smarter than the people making use of it you could simply instruct it not to reveal information that would enable a potential competitor to construct an equivalent. No need to worry about competition; you can quite literally take over the world at that point.
Not that I think it's likely such a system will so easily come to pass, nor that I think humanity could manage to maintain control over such a system for long. But we're talking about investments to hedge against existential tail risks here so "within the realm of plausibility" is sufficient.
