increasing the block reward a little bit

Topic: How many Bitcoins have been provably lost? At least ... - page 2. (Read 2474 times)
I'd like to know whether or not the bitcoins sent to nonexistent public keys should be left lost forever or somehow put back into the ecosystem via increasing the block reward a little bit until they have all been restored (and preventing future coin destruction).
Provably purging coins from the economy may have its advantages, though. Satoshi could send his coins to nowhere, and if bitcoin is ever illegal and the government possesses any of it they can do what they do with ivory: make it stop existing from their vaults.
This is still a pretty dangerous part of bitcoin, because all of these losses have been from faulty coding on the sender's behalf. This loss could have been prevented.

In validating a UTXO parser I started looking at various outputs which are provably unspendable. As of block #305303 2,745.22283996 BTC have been provably lost. The total number of coins lost is higher potentially much higher but most of those losses can't be proven. Funds sent to outputs that can never be redeemed can be provably shown to be lost.
* Zero value unprunable outputs are not invalid outputs but they are undesirable. I was surprised to see there are over three thousand in the UTXO. In the future the creation of new zero value outputs (with the exception of the prunable OP_RETURN) could be made invalid and potentially even these outputs pruned off by a hard fork.
** As of block 305,303 the coin supply is limited to 12,882,575 BTC. This is based on the max subsidy per block and the block height. However the UTXO (set of all unspent outputs) is only 12,882,439.79102854 BTC. Some of the difference may be due to OP_RETURN outputs (which are unspendable by protocol) having a value set. This could be accidental or intentional. Another source of lost coins is due to miners taking less than the maximum block reward which in effect "de-mines" an amount of coins equal to the difference between the allowed reward and the taken reward.

How is this happening ? Is not the reward scheme in the protocol ? Does a miner have choice for his reward ?
