Hearn simply does not understand bitcoin.
He thinks it is suppose to be Paypal with super fast transactions.
What's do you mean?
Hearn and Gavin want Bitcon to scale on the main chain,
which is a no-brainer good idea.
It's Greg Maxwell/Blockstream that
want Bitcoin to be a settlement layer.
Why increasing blocksize is a good idea? It will kill decentralization which is already a problem for bitcoin. The chain is already over 60GB.
I'm not sure why they even discuss this, there is no problem. Hearn wants fast transactions, I'm not sure why he even worked on bitcoin, he should have started his own altcoin long time ago. I guess now he will.
You want fast transactions?
You pay for it. Problem solved. Next.
The block size growth should be kept below decline of hardware prices. Otherwise you pushing cost of running the network on miners and nodes. Running a node is already a form of taxation. Decentralization is a key feature of bitcoin and it should be protected, IMHO.
