Mana is what fuels magic in this setting, and mana is more than simply energy. As Runya puts it, it is "life itself" and in its natural state it can't really effect the physical world much (albeit mamono mana can since it can feed off the desires of those it interacts with, and said desires will alter it to perform functions). In other words, it is a particular form of energy and to be used for magic it must be altered by a mind. And it can be used to outright trump the laws of physics, so again I don't see how zero point energy would be such a game changer.

Not to mention even a cursary look at info on it reveals that there is still a lot about zero point energy that scientists don't agree on, as well as that most physicists overwhelming reject the idea it could be used as a weapon or to even obtain useful energy to perform any kind of work. Heck, we don't know if zero point energy even exists in the MGE world, but we do know that the physical laws of the real world need not necessarily apply to the MGE world.

Overall I am still at a bit of a loss as to what your point is in this. Its an RPG style magical fantasy world, why bring all these real world theories into it and then call the setting dumb for not utilizing them to make characters infinitely powerful? True, infinite energy gain does exist in theory in the setting, but at higher power levels the power gain is so slight and small that its often inconsequential (KC mentioned this when asked about nine tailed fox power growth, noting that once a being reaches more than low rank god power, power growth slows greatly), so its not really comparable. Characters in a given setting use power sources that the author says are available to them, they shouldn't be required to account for every theory on possible real world power sources.

Also, magic to manipulate or use time doesn't seem to exist in the MGE, at least as far as it being a resource for power. The closest we have to a reference to it is how Pandemonium is a spirit realm where time doesn't effect things.
