One of the pillars of capitalism is the idea of "creative destruction" (https://en.wikipedia.org/wiki/Whale_fall). That is, when a moderately-sized company falls apart, it's actually a long-term positive for the economy as a whole. It's decomposed, sold off, and its former pieces are repurposed for the good of all.
One purpose of antitrust law is to keep the cycle of whale falls going. If antitrust law is unenforced, the whales never fall, which has a negative impact on the fragility of our economy: if and when these megacorps become anemic, they threaten to take down the whole economy/whale-decomposition process with them.
