Let's take JavaScript for example. (I worked on the original versions of JScript at Microsoft from 1996 through 2001.) The by-design purpose of JavaScript was to make the monkey dance when you moused over it. Scripts were often a single line. We considered ten line scripts to be pretty normal, hundred line scripts to be huge, and thousand line scripts were unheard of. The language was absolutely not designed for programming in the large, and our implementation decisions, performance targets, and so on, were based on that assumption.

>а зачем ограничивать доступ к полям структур, неясно.

Скорее всего, имеется в виду доступ к полям прототипа, там, где это не нужно. Например, при обходе циклом for in. Признаться, на практике никогда не имел с этим проблем, хотя книжки советуют проверять hasOwnProperty.
