Gold's block reward is adjustable. In times of low population growth and low economic activity, it is very near to zero. It can also reach upwards of 2% per year in boom times. Since antiquity, it has averaged only 0.3%, much less than is probably needed for network security alone.
On the other hand, the fiat regime since 1971 shows the terrible mislocations of capital caused by the "contained" inflation averaging 6% per year.
0.7% per year => monetary base doubles in 100 years, goes up a 1000-fold in 1000 years.
1.4% per year => monetary base quadruples in 100 years, goes up a 1,000,000fold in 1000 years.
2.1% per year => monetary base goes up 700% in 100 years, a billionfold in 1000 years.
2.8% per year => monetary base goes up 16-fold in 100 years, a trillionfold in 1000 years.
3.5% per year => monetary base goes up 32-fold in 100 years, a quadrillionfold in 1000 years.
Anyone who takes the time to read the above list, realizes that no astute whale is going to buy things whose inflation is more than ~1.5% per year unless they are for short term speculation only, or there is another compelling consideration except inflation.
Nonsense. You are not investing for 100 years. The nominal rise is meaningless. If the population + productivity is growing at the same rate, then there is 0 (ZERO!) relative nominal growth.
You are exaggerating because you don't show the relative figures.
I suggested the long-term rate of debasement should mirror the population + productivity growth.

So that is a range between 1.3 + 1.7 = 3% to 2.1 + 2.05 = 4.2%, i.e. 3 - 4%.
