OP, but what mechanism would you propose to protect the network from the entities that would flood the mempool to increase the fees, and therefore, according to your proposal to maintain 1%, would increase the block size so much that many of the nodes that do not have the hardware and the bandwidth will not have the ability to keep up?
I fail to see what would be the incentive to launch this kind of attack as the attacker can't generate more income or reverse a transaction by increasing the block size limit.
That still doesn’t mean that it couldn’t happen. For Bitcoin, currently being a network with over a $trillion in market capitalization, the developers should NEVER risk and give any way for bad actors to exploit and disrupt the system. The network should be FULL PROOF as possible.
