It's called you're a moron because in any system with no minimum transaction fee, the blocks will always be full even if you raised block size to 10 gigs.  All that matters is what the price to get included in a block is, but no blockchain is suitable for microtransactions in the first place.  Even with 10 MB blocks, all small transactions would be pushed off-chain onto things like the shift card or second tier solutions like Lightning Network.  It will never be economical to do microtransactions (buying a pack of cigarettes) using a blockchain.  Blockchains are only suitable for high value transactions or settlement layer.
