And what if you are used dynamically typed language for years and still cannot understand why anyone would choose on if can chose freely?

Seriously I have noticed that static vs dynammic preference is quite sustainable thing for people. Even if you are have used lot of both most people prefer the one they are used when they 'got it' during their programming learning path.

I don't really understand that CSV example what's the problem but one concrete challenge I have noticed with static types is when you want do mutation which effectively change the type. Instead of setting just new property you have to potentially do dummy copy (including type) or some additional hashmap by id for this additional data.

(btw I am not your down voter)

I went back and forth between typed and untyped languages. The sheer drudgery of typing out and visually filtering out while you read the obvious type information is what makes typed language feel way less fun for me. When you cut things out move them around, delete them, retype them, throw everything away again and start over... I'd never choose Java for initial implementation of anything.

I'm not sure why other people like dynamic languages but there must be some advantages.
