Undertow can be strong. Even strong swimmers get pulled out. There will definitely be more deaths. Many will be young people, lives not really worth much in damages. I’d say on balance probably cheaper to let people die. Still, glad I got that one save back in 1977. I would not let my kids swim in the oceAn even though the older one is a superstring swim team type swimmer, not without a lifeguard. Too risky in calif, beware the undertow.
