The complexity you introduce trying to achieve 100% uptime will often undermine that goal. Most businesses can tolerate an hour or two of downtime or data loss occasionally. If you set this expectation early on, you can engineer a much simpler system. Simpler systems are more reliable.

Much less expensive too.

I think in general that expectation is NOT acceptable though especially around data loss. Because the non engineering stakeholders don't believe it is.

Engineers don't make decisions in a vacuum, if you can manage the expectations, good for you. But in most cases that's very much an uphill battle which might make you look incompetent because you cannot guarantee no data loss.
