This is a very good point. Thank you for bringing it up.
It is my understanding that as the platform grows (and it is growing fast now!) that there will be a need for more witness servers to keep up with the growth of the platform. In order to incentivize new witness'... adding one extra block for a new witness to produce should do the trick... and a 5% paycut shouldn't matter if the currency is doubling ;)
The stake weighted inflation is BS. The revolution will be on the blockchain... but this type of BS is perpetuating the same old same old.
Thanks!
