It can cost a lot, if you use it in a loop it can count for a big chunk of
the process.

Maintaining type safety how?
In reality you lose the type safety, when you box an int for example you
will get an object reference, you could try to cast it to any other type and
get an error, unfortunately this error will be detected at runtime and not
at compile time. so it does not help but quite the opposite.

Not at all, they are two very different things.
