Lactate is a waste product to anaerobic energy production.
Blood Lactate is now seen as a proxy who's level goes up and down parallel to a bunch of other physiological changes that are believed to cause fatigue. In essence, it is not wrong to state that Lactate is a waste product since you will slow down anyway as its level increases.
As for the aerobic vs anaerobic metabolism's rate development, they are mostly conditioned by the efficiency of Enzymes responsible for supporting these processes. Like you mentioned, that is taking place within the muscle fiber itself.
These Enzymes are like the employees in a shop. Training aerobically will in turn train the employees responsible for operating the aerobic metabolism to do their job faster. The result is that this metabolism will operate at higher rate. Whereas training mostly anaerobically will train a different employee department. So it's a major thing. Especially since these employees aren't even working out of the same building at all.
Aerobic employees work in buildings called the Mitochondria, which you find in greater number on the Slow Twitch Muscle Fiber Boulevard. Purely anaerobic employees work in plants found on the Fast Twitch Type IIB Boulevard.
And there's a special category of employees who work in plants on special Boulevard called Fast Twitch Type IIA. These are probably the most important employees to train (both aerobically and anaerobically) since your ability to perform a fast 100 highly depends on the efficiency of these special muscle fibers.
Maglischo was the first to teach me about the fact that En2 (threshold pace training) was a great way to train these muscle fibers. And this really explains why he recommends sprinters to train aerobically on this pace. More Fast Twitch Type IIa specific.
Although a lot of aerobic energy is needed to convert lactate back to sugar, this process isn't done in your swimming muscles, and does not benefit your aerobic swimming at all.
If you refer to this mysterious process during which the Liver converts Lactate back into glycogen, you're absolutely correct. This process in fact kind of slows you down. It ain't aimed at helping the working muscles, but rather to make absolutely 110% positively sure that your brain will never lack blood glucose. So this glyco is likely going to be converted back to glucose where it will travel the blood stream up to your brain.
THAT said though, aerobic contribution to lactate metabolism isn't limited to this mysterious phenomenon. Not at all. Quite simple Q. Lactic Acid becomes Pyruvate which can then reenter the mitochondria for being oxidized. I think that this process is often referred to as being Cellular Respiration. This way, Lactate is definitely considered as a fuel, a powerful one. And it helps boosting your swim endurance pace velocity as well as delaying severe acidosis (resulting from sprinting a full 100 for instance).
So in the end, training anaerobically vs aerobically might train different muscle cells (TypeI vs TypeIIa vs TypeIIb), might train different enzymes which operate in different places.
