No one is agreeing or disagreeing with what you're saying because no one understands where you're coming from. You've basically said "Green is stupid because we're still using cars!"
Design aesthetic is different from 'stuff that doesn't work'. I'm reminded of design students that create something that looks like a bicycle out of cardboard layers, and say "See! I've improved the bicycle! It'll change the world!" And what they have is a useless sculpture of a bicycle.
It's plain to most folks, using ordinary bathrooms in ordinary houses that the stuff is laughably awkward, dangerous and hard to clean. Try to explain it away all you like.
Again, we were speaking about durability and aesthetics, not functionality.
Since you want to discuss functionality...
> laughably awkward
For example? Do you have any better real world alternatives.
> dangerous
What and how?
> hard to clean
Compared to?
> Try to explain it away all you like.
No one is trying to explain away anything. We're not talking about the same thing. You're interjecting your thoughts on functionality as if they're in opposition to our discussion about reliability and design.
To put it another way, we're talking about reality and you're arguing hypothetical. It's like showing us how your air guitar is better than our actual guitars.
Remember those two faucets that used to be on sinks, one hot and one cold? Got replaced by the lever-valve that you push right or left to adjust temp? Took a generation to switch, though the benefits were obvious the first day.
Well, those two faucets go back even further. Watch any old cowboy movies? In the rooming house, the wash stand with the enamel basin and two pitchers? One pitcher hot water; one cold. Mix in the basin, then wash and shave.
When plumbing happened, the basin got set into the wash stand, a drain put in the bottom, the two pitchers replaced by two faucets.
Then, for about 100 years, nothing. No progress. Just that old familiar setup without modification.
Finally the kids were like "hey! I'm not filling that dirty old basin with water and washing in there! I'm just washing under the running water." The basin became simply a drain. So thus the impetus to combine hot and cold. So you didn't alternately scald and freeze your hands.
The 'modern' bathroom sink took 100 years to come about. Not because to took that long to invent. It took only a moment to see the advantages. What it took was, 100 years for the old, hidebound folks to pass away and let the kids take over.
I'm convinced our bathrooms are the way they are (weak explanations notwithstanding), because people are slow to change.
