Well, anti-hero is not the word that should be used in this context at all, anti-heroes are always known for being unethical, do whatever they want no matter the consequences and sometimes doing heroics actions but unlike heroes, they will kill the villain or create some casualties and they won't care about it.
The MCU tries to be realistic at some point with the Winter Soldier and technically Captain America Civil War, but after that, they went all family-friendly so the casualties and million people than died because their battles have never been mentioned again.
I share your toughs about that, I like superpowers, I think they are cool, but if you put one character with superpowers in an environment like our world, all the situation becomes boring, the character would never risk anything so being a superhero would be a fun hobby for them. Yes, I know that characters like Spiderman have life issues and the X men have social issues, but they are a walking weapon so besides their emotions they don't have a real challenge. Yes, I know that mutants died in movies and comics, but I'm unaware of how most of they died and in the movies most of they "died" off-screen so I'm still wonder nowadays how someone as powerful as Jean would die by a telepathic attack when they established in previous movies that she can be strong enough to nullify the attack, even in the Dark Phoenix retcon she is almost immune, so how she died at the end if she is so powerful?
Well, it's not a question to answer in this post, the point is, that I prefer to create in my comic a world where everyone has powers, so you could experience the coolness of the powers but at the same time the challenges of the real heroism in certain situations, the characters have powers, the animals have powers, and even magical objects exist so anything can happen in many levels putting lives in risk.
I think that would be more balanced and you even can see how the characters are affected by the events that they face eventually.
