>no reliable way to get a fixed income

You could buy an annuity from an insurance company. A quick Google search shows that $2mil should buy a 40 year old about $70k/year for the rest of their life.

That would be an incredibly awful deal for a 40yo, since it’s not inflation adjusted, so in 10 years you’ll be kicking yourself for having converted real assets into fixed nominal returns.

Annuities really just work well if you are 80+ and want to insure against longevity risk.

An annuity would not be a good deal unless you're in extremely good health and over 75 or so.

State-issued debt from eurozone countries or the US is essentially risk-free. Any of them defaulting would mean they effectively stopped to print cash, at which point one should probably start growing their own chickens.
