What special interest groups neglected to tell you about the block size issue:

From an economics point of view, trying to force the entire planet onto a fixed block size with low scaling is a pro-usury extortion stance.  Small blocks are a synthetic monopoly.  If criminal banks believe they can take control of this monopoly, either through getting a large percent of the transaction validators, or by taking control of all services that facilitate off-chain transactions like Coinbase (or lightning) since on-chain transactions are too expensive to use, then the criminal banks would likely support small blocks over large ones.

The solution to the problem is not 1 MB or 8 MB blocks.  Any system with a fixed block size is going to inherently be a pro-usury extortion scheme due to synthetic monopoly.  You would need to use a dynamic, scaling block size like Monero to fix that.
