I'm going to concur with the OP's argument, but I want to add a couple of comments:

Voice acting in games is generally a bit overrated. Text can work really, really well. When I was playing JRPGs in the 90s, I was never bothered by the lack of voice acting. What those JRPGs did really well was making the characters really really expressive. You could feel their voices.




Another example of text working really well is the storybook sequences in Pathfinder: Kingmaker.

But voice acting can add to the experience, if it's good acting. Personally, I think it's also better for it to be consistent. The main character should be voiced, otherwise the absense can get distracting.





For comparison, this Fallout 3 conversation suffers for its absense. The dead silence is a bit jarring.



I'm not going to be bothered by the main character being voiced in the "wrong way". Even BoF3 (one of the example videos I included above) took this concept too far to the extreme by having the main character literally never have any dialogue (ie not even text). God forbid the player character accidentally have a personality. The player character should just be a lifeless boring husk for you to project a personality onto, I guess.

The only time I've had a problem with a voiced player character was recently in Cyberpunk 2077 when I noticed that the female voice actor had a bit of a slur that started to grate on me after a while. But generally, if the character has a neutral voice then it's fine. (I also think also the writing for the player character needed a bit of work.)

The bigger issue is multiplayer and other parties filled with player characters. One thing that really doesn't work is having 4 player characters with the exact same voice. Adding to this, I understand Larian is going to allow you to play as Gale and other voiced "origin characters".

My understanding is that having 2 voice actors (one male and one female) for the player character including all dialogue options is not prohibitively expensive at all, particularly with the budget of AAA games that BG3 has. However, multiply that cost by 4 or more, and it's harder for me to make that assertion.

So I don't know if it's reasonable to expect the player character to be fully voiced given some of the features that Larian is planning. XD
