Its pretty clear that you don't understand what youre reading. What you quoted is a great explanation of why inflation is not a significant factor when holding steem.
Yes incentives increase the supply of steem (as free and as steem power), and thus, theoretically decrease the value (provided the current market cap is a reflection of the real value of the currency as a whole)...but it gets basically (mostly) distributed back to the people who had it in the first place.

ALso, though it doubles every year, its a cycle because it also splits into 1/10th after a time... ultimately, the supply is a wide but fixed range.
