He contains a lot less energy than 2H as you can see in this graph. Also you shouldn't see this as "usable atoms" And instead as mass-energy in general. Stars reduce the total mass-energy usable in the universe due to wasting a lot of it towards entropy. Stopping stars from burning gives the species 21 orders of magnitudes longer existence.

>universe will exist for 500 billion trillion years but let's recycle all stars to get extra 20 billion
No you misunderstand the scale here. The last star will burn out 100 trillion years from now.

Which is 1*10^14 years from now or 100.000.000.000.000 years from now. This is when all mass-energy in the universe will have been wasted towards entropy.

If we stopped all stars from burning and gather all mass-energy in the universe we'd live for 1*10^35 years.

Or 100.000.000.000.000.000.000.000.000.000.000.000 Years

So you'll exist for 100.000.000.000.000 years or
100.000.000.000.000.000.000.000.000.000.000.000 years.

And the only cost is launching a SINGLE self-replicating von neumann probe that snuffs out all stars and slowly gather all matter in the universe.

It's time to recognize that seeing stars in the sky is DIRECT evidence of no advanced species existing in the universe.
