I gotta admit I don't know what 50% of the words there mean, but it surprises me to suggest that "absolute integrity" would not be required for trading, escrow, DeFi, DAO/access tokens.

Makes sense for games and art (but then I wonder what they are doing using a blockchain in the first place).

zk rollups tend to inherit most of the security features of L1[1] but with some trade-offs.

The trade-off is basically scalability (and thus fees). If the L1 network is so highly congested that each transaction costs $100 or more in the future, a scalable zk rollup that achieves about the same level of security at the cost of < $0.001 may be worth these tradeoffs.
