if you can enumerate these reasons and demonstrate that they don't apply any more, then you are in a good position to change the thing.

If you don't know what these reasons are, it is hard to know with certainty that they no longer apply.

see above reference to Chesterton's fence.

I don't see it that way. People are creatures of habit and prefer to torment themselves with existing problems that they have learned to deal with rather than get involved in something new.

People also love to create and get new and shiny things. Combine that with force of habit, and you get truckloads of engineers that tear down and replace what was working and only needed maintenance.

Both forces exist, the important part is to balance them properly.
