Really though? During that time, you occupy a space, and the spaces afforded you by the society you are born into define the constraints within which you can apply your time. That is, all of your "currency you are born with" is really "futures".

Even the time on Earth you are allotted at birth is constrained by the environment you are born into.

Lots of people are born with wealth. In fact that biggest factor in how much wealth you have is how much you are born with.

It’s certainly the most valuable natural resource a person is born with, by far, but I’d argue there’s also technically space and energy there, too. The space a baby consumes is almost valueless, and the energy output is also (though thoughts of babies being harvested in The Matrix come to mind).

Energy - or rather, the ability to convert it between various forms, like food > kinetic energy - is also a currency that we are born with. If you have grown very old, even having a week on hand will not help you lift a sledge hammer.

I'd say you're also born with energy if you're born with time.

People are born with significant variance in other "currencies".

Spacetime is a better description, and it’s full of real estate. Mammals at least are born with a deed or a need for a boobie, or in big trouble. It’s all linked!
