It might not be believable

The problem with this Civil War occurring at this stage in the Marvel Cinematic Universe is that it might not be believable. What we mean by that isn’t the fact that there will be fantastic superpowers on show that aren’t “realistic” – we simply mean that the feud between these friends might not make much sense at this stage.

The last time we saw the Avengers together – in 2015’s Avengers: Age of Ultron – they were the best of friends. Even Tony Stark and Steve Rogers were starting to genuinely like each other, so for them to want to go to war with each other so abruptly is a little out of the blue.

A violent feud should have been hinted at for a longer period of time for it to be believable. Sure, the Avengers have bickered among themselves, but not to the point of wanting to kill each other. There’s a very real risk of the feud not seeming authentic.

And then there’s the possibility of linking it to a future movie.
