If the block-reward halves every 210,000 blocks (or every 4 years'ish), then it will halve 5 more times by the time 2033 rolls around. History has shown (not only with Bitcoin but with alt chains as well) that when a block reward halves, supply halves, and thus the market value doubles. There's some "ramp up" of the price in the weeks preceding the halving, so it's hard to isolate the actual dollar value that will be doubled.
Please stop being innumerate.
Do you really think the price of a durable commodity is inversely proportional to its rate of production? Reductio ad absurdum: if gold mining were to approach zero, the price of gold would approach infinity, even though the total amount of gold in the world remains the same. Please.
