So you are making a lethal weapon of financial self-defence, which the system cannot destroy, and therefore you (the system and the people) will learn to respect the mutual differences?
Well I just proposed the exact same!
Isn't it so elegant to discover that the best arrangement for the free market (i.e. no futures contracts which is the Proverb I learned from Hommel, "Do not be surety for another person" and I refined more as per below) in making each development autonomous from the succeeding ones (and let the market decide to burn their coins to the next improved fork) is also the one that is legal.
The point is do not promise the future, because the further away the future, the less control one truly has. Better to sell what you have now, then in the future sell what you have then. Gives the markets more degrees-of-freedom. This is why Ethereum's lockup of shares for so long was so evil.
An example of degrees-of-freedom is that some other developer could also offer a fork that coins could be burned to. Competition increases performance. Another example of degrees-of-freedom is imagine your car with a reverse gear, you would need to drive around the block to go backwards. Or imagining tying your shoelaces together, then you can only hop instead of walk or hop.
