Yet those who stake tezos are (and they will probably always be) an initialized majority , they will always be the generation of 2017-2018, their descendants, heirs and friends. And this creates an assymetry over time, which may or may not be fixed (as you correctly say). But , knowing the human nature, the posibility is it will not be fixed, because greed always prevails. Future generations will understand the greed of this generation, and they will probably hard fork tezos, the same way they forked ethereum or bitcoin today.
There are cryptos which are trying to solve this space-time assymetry, for example duniter. I hope that tezos holders will have a closer look at it, and they will understand the value of the time-space symmetry of the money distribution.
Furthermore, there is also another fundumental problem with tezos, and this is the proof of individuality. Tezos will be succesfull only if it manages to compete the current worldwide monetary system. The holders of the currenct worldwide monetary system have huge power , and they may buy tezos in order to stop its governance, and lead it to decline. Thats why the tezos community should know the holders and the way they decide. Not their real name of course, but the way they vote and decide through time. And this can be achieved only if a proof of individuality is implemented in tezos. that will associate unique individuals with the number of tezos they hold and the way they vote.
Because no matter how many tezos you own , you may still vote in favor of yourself and against the community. And of course what it counts is not the number of tezos you own, but how much your whole fortune is. If tezos competes euro and your fortune is 99% euro and 1% tezos, you have no incetive to take good decisions for tezos, even if you hold 51% of the whole tezos. This is the case of the states, they hold 100% of the euro, and if tezos prevails and destroys euro they will hold only the number of tezos they buyed (for ex. 51%). And this is against their interests. So state agents will try to buy tezos in order to boycott it and decide against the common good of the tezos community. Thats why a proof of individuality is needed, in order to spot the agents. And then the community of the individuals may decide to diminuish their voting power, no matter how many tezos they hold.
