The purpose of safeguarding reserves would be to secure project longevity, and to maintain/build market confidence in the project and its valuation. This project is very experimental, and an ambitious vision such as creating the world's decentralized reserve currency is going to take a lot more than 2 years from today. The experimentation, iteration, innovation and engineering required to reach the vision will require a tons of funding. Reserves = funding.
Also, at the extreme sad end of it, wouldn't there just be:
1 last OHM left,
0 liquid backing left
32.5M worth of vested assets
Might be a good deal for the OHM owner, assuming ofc that the vested assets really are worth 32.5M and transferrable?
Fun picture: US Treasury seems to have been running Inverse Bonds on their gold between 1960-1970 until they realized its not going to end well and said to hell with our commitment; nobody is gonna claim no more of our reserves.
