That's not true at all. The decision makers in Ethereum care overwhelmingly about maximizing the value of their massive premine holdings. The latest EIP-1559 proposal (tl;dr ETH gets burned in every transaction) makes their stash an even larger percentage of the overall ETH distribution. Which is even more egregious when you learn that proof-of-stake rewards those with the most money (read: the decision makers).

I don't buy into these second layer solutions. They are still limited in terms of scalability (they just push the limit back a bit) and operational complexity tends to get out of control and that makes them much more vulnerable to exploits (especially DoS attacks which attempt to prevent or delay state changes and attacks which try to roll-back state changes).

That seems like a shortsighted position because it ignores the cost of selective enforcement. Everyone breaks laws on a daily basis - jaywalking, speeding, etc. - and you could have a severely disproportionate cost by enforcing that more for one group than another, even with every trial being completely fair.

Here in DC there was an example awhile back prior to legalizing marijuana: white people apparently used at a higher rate but most of the prosecutions were of black people both due to heavier police presence and because demographics meant that white users tended to have more privacy (limited visibility from the street, more distance between houses/sidewalks to make smell harder to notice, etc.) which made it harder to get evidence clearly showing that a specific person had been the one using. The process could be fair without changing the fact that the results disproportionately impacted one group.
