I believe it's part of the experiment, and I don't think everything will fall apart especially in this part of Bitcoin's evolution when the self-interest of each participant must find some balance with the interests of the group. Eventually, the participants will come into consensus to find the balance where everyone is incentivized to keep everything running, and to keep everyone participating.
There are certain principles that Bitcoin was built upon like pillars. You can't say if these principles (consensus) are changed things won't fall apart because the result will no longer be Bitcoin as we know it.
and the Big Blockers who were debating for a block size increase/Hard Fork.
Lest we forget, The problem wasn't
just that they were arguing for bigger block size, the problem was that they were arguing that block size increase should be the
only solution to scaling bitcoin.
Their proposals were also crazy like saying block size should be "unlimited" (eg. 2 TB blocks which later on turned into shitcoins like BSV) or they argued that the miners should have full control over the future of block size and decide whether they want to increase it and how much.
This is why their proposals never got anywhere, otherwise I personally believe that the block size itself should be increased by a hard fork at some point in the future but the main scaling solution should still be a second layer not the block size.
