But you would not be able to collect the cash from a bank without all kinds of due diligence, or process alarms going off.

In Switzerland it used to be quite easy as the money belongs to you and you can do with it what you want. The only issue should be depositing large sums.

If the banks make it harder and harder to get your money out then of course things like bitcoin are getting more popular.

I can't actually speak for Switzerland, it does have a reputation for "no questions asked" banking.

Meanwhile, in other parts of the world, "Know Your Customer", "Due Diligence" and other Anti-Money-Laundering measure are important. (1)

I think your last point is better phrased as "If the banks make it harder and harder to get your money out in bulk, without proof that your transaction is legal; then of course things like bitcoin will be used for the illegal transactions. And as a result the regulators will sooner or later regulate those too".
