I'm not trying to argue, just verifying the trade-offs wth a back of the envelope calculation. 

The goal is to maximise participation in running nodes, but there is not much point running a node if you can't afford a transaction. 

The block size means there are a maximum of 4000 transactions every 10 min. That's 210,240,000 transactions a year with full blocks. 

Even if you saved up to add to or withdraw from your retirement savings once every 10 years it only allows 2 billion people to use Bitcoin onchain. What are the other 5 billion meant to do? 

I'm not arguing for larger blocks. It's an inefficient scaling solution and one that is not beneficial for a long time. We should develop the scaling solutions cautiously first, because these could become more different to implement as time goes on.
