You picked a particularly bad example. Structuring is a notoriously bad law because innocent people make transactions that would be considered structuring all the time, and making it illegal has no legitimate purpose when the government could just use the aggregate amount of deposits over some period of time for its reporting threshold instead of the amount of each individual deposit. It's like creating a rule with a loophole that gets exercised through ordinary behavior, and then instead of closing the loophole they impose criminal penalties on the ordinary behavior.
But then you consider that it's used for civil asset forfeiture (i.e. law enforcement stealing money from innocent people without ever proving a real crime) and it suddenly makes sense:
Whereas with MSFT it's a different situation. There is nothing illegal or wrongful about depositing a large amount of money, there is just a heinous law that makes it illegal to do it in a common way. Whereas monopolizing a market is intended to be illegal regardless of how you do it, so there shouldn't be a way to structure things to monopolize the market without breaking the law. The way you're intended to comply with the law is by not monopolizing the market.
