This is a special breed of stupidity:
Bitcoin block rewards will eventually become infinitesimal, at that point transaction fees will be the only rewards miners get. Right now transaction fees are around 0.1-0.5 BTC per block, which is nowhere near enough funding to secure the network by itself. We need transaction fees to go up, and the only thing that will force them up is the blocksize limit. Increasing block size might cause fundamental damage to Bitcoin due to this.
Larger blocks with more transactions will have more transaction fees. PLUS the fees become more valuable as bitcoin increases in price, even if the percentage of the transaction the fee represents gets smaller and smaller. This is because as bitcoin becomes a more viable alternative to ACH, SWIFT, Western Union, Moneygram, remittances, wire xfers, etc, many more people will keep a small stash of BTC as a hedge against fiat onramp blockage.
Miners do not have to include microtransactions in their blocks, but some do. So large transactions with fees are on average faster. There is a market for speed by design.
Chainbloat is the price we pay for disruptive competitive advantage over legacy systems. It makes us incrementally more vulnerable to some malicious attacks and much LESS vulnerable to others like transaction backlogs. It's a cost of doing business and a ridiculously low one compared to legacy networks' cost of doing business. Successful miners aren't the ones obstructing progress here. It's the inefficient miners and those attempting to subsidize their inefficiency who are.
scale or die.
