>Digimon are spawned by the digital world as it spawns
This isn't vague, the world makes more digimon as it gets bigger. What's not explained is the very specific mechanism of it which isn't a problem because its not important other than giving an explanation of how the population size increases. There can be a limit to the amount of digimon on any given digital world as shown through the x-antibody story line however.
>Digimon do not carry out reproductive activity
This line definitively states they do not have sex, again you can goon all you want buts its not support by anything official.
