We could disregard "Mudd's Women" by the same token - utter shit in terms of drama, so clearly dilithium cannot be mined and Harry Mudd never met our heroes before "I, Mudd", which can also be disregarded and thus Norman the Android never existed and since "What Are Little Girls.." also was poorly written, Data really can be unique in his androidness...
Really, some of the dilithium technobabble in "Alternative Factor" can be considered not just its saving grace, but actually pretty fundamental to our understanding of treknology. We get an early version of coaxing dilithium back to life, as later seen in ST4:TVH. We get to see what Starfleet dilithium looks like, rather than the emergency "field repairs" solutions seen in "Mudd's Women" and "Elaan of Troyius". And we get "energizers", plus some data on what works and what doesn't without dilithium...
OTOH, we could assume that our heroes talk about antimatter in a figurative sense when they discuss the risks of the two Lazari meeting. Or we could read a bit extra into this exchange:
Lazarus: "You understand."
Kirk: "Not completely. This is a parallel universe?"
Lazarus: "Of course."
Kirk: "Antimatter?"
Lazarus: "Here, yes."
Kirk: "And if identical particles meet-"
Lazarus: "The end of everything."
What does the odd "Here, yes" mean? Apparently, the risk lies in the mad Lazarus meeting the slightly less one in the parallel universe; perhaps there is no risk with the meeting taking place in Kirk's own universe? Perhaps one is antimatter and the other is matter only "here", while both are matter "there"?
Note also that the mad Lazarus does
not use dilithium crystals as an energy source. Kirk's passage drains his crystals, and he re-energizes them with equipment in his ship; the ship is the source of the energy, and the crystals just mediate or capacitate somehow.
