David Friedman is always worth reading.
Making sure we can continue our present activities into the indefinite future makes sense only if we believe that we will be doing those things into the indefinite future. Judged by what we have seen in the past and can guess about the future, that is very unlikely. We do not know what the world of forty or fifty years hence will be like, but it will not be the same as the present world, hence it is very unlikely that we will be doing the same things in the same way and requiring the same resources to do them with.
