maybe ill try to explain my point again, so imagine....

BTC 21,000,000 / Current Circulating Supply / 18,648,793 BTC / Year 2020 / Projected Circulating Supply in 2030 following inflation rate 1.4% = 18,980,000 (for example)

BTC 21,000,000,000,000 / Current Circulating Supply / 18,648,793 BTC / Year 2020 / Projected Circulating Supply in 2030 following inflation rate 1.4% = 18,980,000 (for example)

It would be the same.

So it wont matter FOR US if its a fixed supply of 21 million, because during the course of our human lifespan bitcoin will still inflate at the same rate.

But for people born in say 2120, it will be an issue because there will only be 20 years left before in becomes deflationary, but for all of us born now it has no effect.
