Well, apparently the idea is that there is this DnD universe that I’m supposed to pay respect to. Apparently, having a wizard with a bodak as a pet would be like having Yoda live on Hoth, or something. It wouldn’t “make sense”.
'Cause, you know, having monsters that are amoeba-like blobs comprising of just mouths and eyes, which run around looking for other mouths and eyes to eat, really makes sense.
Admit it, you know what monster I just described.

If you’re referring to gibbering mouthers, then they’re blood drinkers. There are a few other abberations that eat eyes, but none that eat mouths and eyes (unless you’re referring to a Defacer, which has more than eyes and mouths).
As for the pedantic player:
It is in fact unrealistic for a wizard to have a pet bodak, because neither bodaks nor wizards exist in reality. Given that, no claims about their relative realism can be made. It sounds as if this player is terminally unable to cope with the concept of creatures that don’t follow his preconcieved notions of them.
As mentioned, Pun-Pun is an excellent cure for this type of ‘thinker’.
Also, as a DM myself, I can say that by deliberately not limiting the players, you can get much more interesting campaigns. As has been said, it is always your responsibility to, when a player tries to do something, figure out how it can be done.
A side-effect of this is to give up entirely on plotting adventures in advance. I just make a list of the notable NPCs acting in a current time frame, and what their goals are.
It makes things very interesting when, for instance, the werewolf the party was hired to kill is given his own bounty as a down-payment on a mercenary contract to join the party and unleash lycanthropic hell on a nearby tribe of orcs.
You can also get some wonderfully amusing PC actions when the players know that they can do anything, and you can do anything to them. One BBEG expected a break-in by the heroes at one of his facilities, so he made sure to put an extensive collection of forged evidence claiming that the current PC quest-giver was responsible for all of the war and unpleasantness in recent campaign history, and to be very careful about the evidence because if the quest-giver knew it existed, he’d give up on his current subtle plans and go back to the wanton slaughter, which the BBEG was piously trying to avoid. All a load of bull, but the BBEG was demonstrating that BAB and Str modifier do not an effective villain make.
You can guess how the party reacted when they discovered this ‘plot twist’.
