The joke is on you guys. Block rewards = inflation, and Bitcoin will be in its inflation stage for quite some time.. Our entire lives. At the current price, Bitcoin needs $597,187,500 USD to come into the market yearly to retain its buying power and current evaluation. That is an inflation rate of about 9.8%, as to the bolded...
Well you are correct that BTC is currently inflating and will continue to do so in monetary units until 2140. But technically in the currency marketplace despite Bitcoin inflating in supply it is acting as a deflationary currency because demand outstrips supply. So over the last 5 years USD fiat has lost 99.9999% in value against bitcoin.
the USD is currently inflating by 2%. 
lol... you are drinking the koolaid if you believe this. You are using the incorrect CPI algo here. Try adding in the inflation from what some would call important resources like food and fuel to get a more accurate level of 5-8% in the US. Inflation level in the US is held "low" by the US taxing the rest of the world because it remains the reserve currency in most trade. Once the reserve currency market share starts to drop further I will guarantee you will see those inflation stats of 5-8% grow.
