Nonsense. What happens is aluminium corrodes/welds onto steel, with time, absence of corrosion inhibitors and exposure to dirty water. Eventually the strength of the bond exceeds the strength of the thread.
It helps to put a very light smear of Copaslip (or Alumslip is better if you can get it) onto the axle before fitting.
Shimano recommend that on all tapered crank arms

Another vote for riding bike with the crank arm bolt removed, never had the correct tool at the time, had to ride for a good 10 miles before it came loose.

I've used drill chuck wedges for this exact problem in the past, something like

I've had success with a ball joint separator tool in the past.
