The wikipedia link that you posted is just bad science, the typical stuff that you read in most textbooks and which is 40+ years out of date.
For example, running a marathon involves much more anaerobic contribution than most authors realize.
Also, the second lap of an 800m race is much more aerobic than people realize.
OK, if the conventional wisdom is wrong, where are you getting your information? About the marathon and second lap of an 800 for example?
"However, faster paced running during base training promotes the necessary neural adaptations we need for racing, so why waste months avoiding faster paced running as many coaches advocate?
I advocate all paces in base training."
When you say "faster paced running during base" do you mean anaerobic repeats or do you mean staying aerobic by running short bursts of about 50 yards without going anaerobic?

As with any subject, there is a huge amount of information which can be sought by googling. Much of it is mis-information, bad science, out of date ideas etc. But if, you search as much as I have you eventually learn what is good science and what is bad. Of course things are open to interpretation, so you then have to keep reading and searching to find out conflicting ideas.
This is my hobby, I was doing this many years ago, but now with google there is so much more info available.
Concerning the marathon and the second lap of an 800, the anaerobic fuel source which we are discussing here is Glycolytic ATP. When glycogen is the source of carbohydrate derived energy, you get 6 ATP per glycogen molecule, but if you read most text, it says 4 ATP per glucose, which is true, but they don't mention that about 80% of carbohydrate derived energy in a race is from glycogen and about 20% from glucose.
In an 800m race we use more of this anaerobic fuel on the first lap and less on the second lap as aerobic respiration increases, NOT the other way round as is traditionally believed. Think about it logically and you will understand that in the firs hundred meters of an 800 you are running very fast, almost sprinting, so you are using more anaerobic sources, and as time goes by you are using more oxidative sources (aerobic respiraton), you are not "going anerobic" rather the other way round.
In a marathon, you will gradually use more and more fat as fuel as the glycogen is slowly depleted, but you will be using most of your glycogen stores, and thus a lot of anaerobically derived energy, much more than the 1% stated in many texts, A LOT MORE.

No, that is the myth I am trying to dispel, you aren't "going anaerobic" during faster paced running, it's the other way round.
