The solution to the block size problem has nothing to do with controlling the size of the blocks. It requires a different design where transaction fees trend near to costs but not to costs, thus not making the nodes of the system bankrupt.
This brings us back to the Cryptonote adaptive blocksize limit combined with a tail emission found in Monero where:
1) The cost of mining a block is set by the block subsidy
2) The total amount in fees per block has to rise to a number comparable to, but most of the time smaller, than the block subsidy.
