It seems to me that even no action at all has that chance, although it
depends in part on what you consider "everything you own".  Your
initial statement suggested a loss as a monetary figure, which is both
easier to deal with and more appropriate to the situation at hand.

I don't deny that there is a definite difference, nor do I claim that
they are completely the same.  I deny that they are *completely*
different.  The magnitudes are different, but everything else is the
same.

And I don't see what making the value "logaritmic" has to do with
anything.  If the value of money is equal to the base ten logarithm of
the amount of money, then the difference between 0 and 100 is equal to
the difference between 100 and 1000, and thus is not infinite at all.

Agreed, at least for any sane value system.  Applying a value system
which gives infinite values to certain situations would probably
destroy game theory.

I can't make that assumption, because it is unrealistic.

It really isn't, though.  No one lives their life with a sole purpose
of avoiding death, or more meaningfully (as it's probably impossible
to avoid death), with a purpose of extending their life as long as
possible.

And even if someone did live their life with a purpose of extending it
as long as possible, now you'd have to define the payout of living
life for a certain amount of time.  Is it worth a 1% chance of dying
one year from now for a 99% chance of increasing your lifespan from 80
years to 90 years?  You still can't separate potential risks from
potential gains.  No matter how much wealth you have, if you had more
wealth, you could protect yourself against more possible ways of
dying.

While it may be valid advice in terms of the situations one is likely
to find oneself in at a casino, it isn't literally true.  The cost of
having to hitchhike home might be great, but it's not infinite.
