The argument is certainly not attempting to be rational.
If you want to break up Apple due to its economic power, then you have dozens of other corporations to slice into pieces. How? Who knows, some bureacrat with likely zero relevant qualifications will get to decide.
If you take apart Apple, then you have to rip apart:
Berkshire Hathaway, 3M, Johnson & Johnson, Caterpillar, Intel, Oracle, Cisco, nVidia, Netflix, Adobe, Activision Blizzard, Priceline, Exxon, Chevron, Pfizer, Merck, Amgen, AbbVie, Abbott Labs, Gilead, Qualcomm, Broadcom, Lockheed Martin, Visa, JP Morgan, Bank of America, Wells Fargo, Citi, AT&T, Verizon, Comcast, Procter & Gamble, Coca Cola, Pepsi, Kraft Heinz, Walmart, Costco, Home Depot, Lowes, McDonald's, Starbucks, Nike, DowDupont, Disney, Boeing, CVS, Walgreens. I'd add GE to that list, but they've decided to take care of it themselves.
You also reasonably have to start dealing harshly with similarly massive corporations HQ'd outside your jurisdiction, when they attempt to operate within your borders. Whether that's SAP, Toyota, Alibaba, AmBev, etc.
Now, on some of those, without question, a large audience is shaking their head yes. For example, the big banks. There is a large segment that overwhelmingly thinks they need broken up. How do you forcibly break up 3M, Boeing and Home Depot? That's just begging for disaster.
Then after you're done screwing with the economy, you have to pass a law that prevents nearly any acquisitions, so the giants outside your borders don't just scoop up the now weaker smaller entities and so that new giants never get constructed again.
Good luck.
