It is impossible to make everyone rich in the first 5 years, where one gets rich the other gets poor. The fairness lies in equal opportunity to buy, meaning supply has to approximate demand. Linear supply provides way more equal opportunity to buy in early or later than any coin with decreasing supply. One mistake in reasoning is to think in terms of dollar value. Grin is a new long term store of value system. A wise investor dollar cost average buy in and will always have bought for a reasonable price.
Are you reasoning that on the long term emission will become to little proportional to the total Grin supply? First of all, for emission to become equal to 2% inflation, that will be in 50 years from now! I suspect 99% of the current crypto projects to have inploded by then because they lack linear or tail emission.
Regarding Grin, you by accident or design ignore the loss rate. Inflation will approximate the loss rate. E g. If there would be a loss rate of 2, Grins security would become 2% which is infinitely better than for any coin with halvings.
Regarding your use of “Igno”, I think if he/she/they would bother to read you article or post they would say
