Last week I changed my chain. It was so rusted it was getting more and more difficult to bend the actual chain. Yeah I know, should have replaced it before. I also had to replace other rusted parts on my bike. Just didn't have the need to change valves. I pump my tires a few times a week. No issue at all. Besides, valve caps on a bicycle are just plain anti.
The fact you let your bike get in that state, then getting picking with most of the bikes in this thread, like valve caps especially, means your opinion is invalid, well at least to me anyway.
