Except that they are also deferring their labor contribution to the economy.
How did they earn the money they spent on cryonics, then?
The free resources in the past didn't lead to compounding exponential growth; why would current free resources do so?
Global growth has been exponential for a long time, even if the exponent is not as impressive as China's 8% annual growth for the last X years.

Where did the resources to put them into cryonics come from?
Consider the few data points in recorded human history: Has the doubling time of economic growth remained fairly constant, or varied widely? Is it more complicated to assume that growth in in general exponential, with the amount of free resources determining the exponent, or to assume that the size of the economy is proportional to the product amount of the mos...
Imagine you accept the main idea of cryonics, that if we freeze brains future technology is likely to be able to extract the encoded information and revive the person digitally. [1] While this currently costs about $120K/person, if we did it routinely to everyone it could probably get down below $1000/person. Which is interesting: the current cost of averting a death is around $1700, but someone who doesn't die of malaria is still going to die of old age, so you can't really say their death was "averted". While someone who is revived after being frozen wouldn't live eternally, they might get to experience thousands of years of subjective life. In terms of life-years, getting cryonics to be really cheap and paying for people to get it sounds like it beats GiveWell's top charities.
Aside from not agreeing that cryonics is likely to work, however, I don't think the value is actually all that high. A future world which would revive large numbers of people we freeze today would be massively different from the current world economically, but would still have constraints. There would be some number of digital people that could run simultaneously on whatever people-emulating hardware they have. Preserving additional 21st century minds would give future people the option to run revived people instead of new people, but I don't think it affects the overall number emulated.
[1] I don't think this is likely.
