If you are financially savvy, or can pay someone else to be, does it not make more sense to invest your money yourself? There are a number of "too big to fail" companies, like GM, and Wells Fargo, that offer dividends. If you composed a portfolio of high dividend, stable, stocks... Could you theoretically have a "guaranteed" monthly income AND the ability to liquidate, in the event of an emergency?
With a stock portfolio, the only guarantee cash-flow is dividends since capital appreciation varies a lot year-to-year. Dividends are usually in the 2-3% range. A large, diversified real-estate portfolio might see 8-15% yearly returns in cash, which can be distributed, saved, or reinvested as needed.
No. You can buy an annuity, or US Treasury bonds, but guaranteed high returns don't exist, and adding in a liquidity requirement doesn't help.
Note that GM declared bankruptcy in 2009. Even if it is still "too big to fail," that doesn't mean investors can't lose all their money.
My comment was to address the question regarding why more people don't use annuities, and I'm not sure your response counters that.
Regarding GM, yes, I'm aware they went bankrupt. But correct me if I'm wrong - Investors didn't lose their shares? The government bailed them out, and they're operational today. That's what I mean by "too big to fail".

The whole point is to transfer money from worlds where you die early to worlds where you die late. An annuity does this by pooling your money with many people living to different ages. For a large pool and accurate actuarial tables, the number of people who die every year can be predicted, so one can determine an amount of money to pay out each year such that each surviving person gets the same amount each year, with long-surviving people getting more total money (as desired).
