I felt that it was less of a cop out than the "Days of Future Past" option. At least here by adhering to the grandfather/boostrap paradox they actually cannot alter the past but only the future. And we all knew that time travel would have to be the solution because how else are you going to bring back characters that have sequels coming out (e.g. Spider-Man Far From Home etc.)?

I would've preferred it too, but objectively speaking sacrificing Black Widow was the more logical choice since Hawkeye has a family. Black Widow's death leaves sad friends in the wake; Hawkeye's death would do the same but also leave a grieving widow and three orphans. Black Widow wasn't just thinking about her friend, she was also thinking about his family; and we know that she's a good friend of the Barton family.

From a story perspective the loss of Black Widow and Iron Man (and the continued loss of Gamora Prime) gave the story more gravitas. It reminds the audience that this is a consequential war. And it makes the ending less of a "cop out" than it otherwise would have been with a time travel story. Yeah, the loss of these characters suck. It hurts. It's meant to hurt. And while Iron Man orphaned his daughter, he did ensure that she has a future to be orphaned in.

Because it's what Tony Stark wished for; he can bend reality to his will. This is what Thanos did when he supposedly wiped out half of all life in the universe, but in Tony's case he wished for wiping out Thanos and all of his forces. Thanos' new plan was to wish for the universe to be reset with the population reduced and never knowing any other reality.

Another interesting point in the movie was when Captain America took time to notice the benefits of Thanos' plans; when he mentioned how clean the ocean was and how he saw a pod of whales (suggesting that the whale population is recovering). This was always the thing that made Thanos such an interesting villain; while the idea of murdering half the population of the universe is abhorrent, the idea of saving the environment for the sake of future generations makes a whole lot of sense. Of course, Thanos could've just wished for more resources and cleaner environments (e.g. wishing away pollution, patching up the ozone layer etc.) instead of killing people, but then it wouldn't make him much of an antagonist.
