Don't think too much of the logistics. Ant-Man 2 showed the characters towing around a block of building, blew it up and shrank it down anywhere anytime. As a grownup now, paying utilities, I wondered. Where was the sewage? How did the piping go?
Ant-Man 3 was a disaster. Even when it was re-running on TV, we turned it off. The biggest problem was Marvel got rid of Ant-Man's sidekicks. Even though they were not the main characters, they were the spirit and the soul to the story. Without them, Ant-Man 3 was lost and went nowhere.
