In enough years, supply could become so limited as to cripple the usage of btc.

Keeping in mind that bitcoins can currently be divided into 100,000,000 spendable units (commonly called "Satoshis"), how many bitcoins will we have to lose to cripple the usage?
If we increase the divisibility of bitcoins in the future so that each of those 100,000,000 units can be subdivided into 100,000,000 spendable units, then how many bitcoins will we have to lose to cripple the usage?
Considering that newly minted units will continue to be created until approximately the year 2140, I'd agree.
No.
This will almost certainly never happen, and since we can just keep sub-dividing the units that we have, there really isn't any reason to either.
Unless some mathematician finds weaknesses in the algorithms, computers will never be fast enough (and there will never be eough power available in the solar system) to brute force a 256 bit key.
