So your argument is that monsters use a COMPLETELY different psionics system than players do, just like they use a COMPLETELY different magic system. Oh, wait...
My argument is Monsters in the MM who have the Innate Spellcasting ability are not using an ability which is even specific to Psionics, much less general for PCs. It is UNQUESTIONABLY not the "rules as written" for PCs. For spells, for Psionics, for ANYTHING.
HOW DO YOU NOT KNOW THIS?
Have you never even DM'ed 5e Max?
