You see a lot of this in home design - because the people who pay for it often have moved on by the time it begins failing (or it's cheaper to install).

Cabinet hinges come in "non-adjustable" varieties which are much more durable and can support significantly more weight, but they're also harder to install.

As for a moving sink you could have it be like a commercial sink "behind the scenes" - just dump straight into a sump (usually called a "floor sink"): https://www.webstaurantstore.com/regency-22-16-gauge-stainle...

People likely don't want that, however, even if you could make the entire kitchen flood proof.
