can you say more to convince me that ETH's moat is based on some kind of network effect? I think the core argument is that decentralization and trustlessness are network effects, and these allow the most users to participate, and I accept this. My concern is that maybe the security only needs to match the level of the transaction, and as such, there's more room for competition from something like say Solana to trade off security for improvements in other dimensions and in the end the users want cheap they don't care about the protocol. What am I missing? (disclosure, I own < $20 worth of SOL)
