The optimal strategy for them is to coerce all the companies that they invest in to only do business with each other in order to completely lock new competitors out of the market. This is very bad for consumers and society.
Please elaborate. What's the right amount?
Why does that matter? Why is 10T too much? It's a big number but that money is ultimately under the control of the individual asset holders (so far as I understand it anyways).
The only conceivable scenario where a major Canadian bank fails and any depositors are not made whole is one where the government has lost the ability to maintain the currency and the Canadian dollar is worthless anyway.

The mutual fund would use the cash to buy stocks or loans and you would be entitled to a share of that profit or loss (both upside and downside), but the mutual fund manager would typically only be paid an annual fee (1).
Money deposited in a bank gives you no upside, and, as you say, a tiny downside risk. (even before deposit insurance) Those taking the downside risk (as well as the upside) is mainly bank equity investors.
(1) As another commenter correctly pointed out there are also other sort of funds that look a bit more like banks for various reasons, but that also doesn't necessarily mean the fund manager is the one taking the upside/downside risk.
Can you explain this part more? Does blackrock not invest its own money in deals? And are specific deals specific to blackrock customers or do they just take a percent of their overall holdings and invest them in individual deals?
What the exact flow is will depend ultimately on how the fund is structured. For example, Goldman will run a private equity focussed fund that you can put money in as a customer, so if you did put money in it, they would invest in similar deals on your behalf. Other customers of Goldman may or may not choose to invest in that fund, preferring something like a bond fund or equities fund etc.
It will take away a small percentage of your money every year to pay costs and make its profits, but you will profit from the returns of the investment itself.
