Hey, so Messari recently put out a report where they claim that an optimistic rollup can run at a max tps of 5.2k, and that's only if rollup batches occupy the entire ETH L1 block (here's the tweet about it) (see the second row "ETH + Optimistic Rollups"). So this got me thinking, does this mean that if activity of a single optimistic rollup takes off for like a web3 game or DEX and it does run at 5k tps, then no other rollups or L1 transactions would theoretically occur on ETH? Taken to its extreme, this would mean that only one high-throughput L2 could settle on ETH, or maybe only a handful of L2s running at high tps (5 rollups running at 1000 tps?), and this can't be correct, right? Otherwise, why are all these groups building optimistic rollups. I know I must be missing something, or I'm hoping that the Messari report is incorrect, but please help me out here. Thanks in advance!
