Go and come

The verbs "go" and "come" have very similar meanings.

Are they really indispensable?

For example if a lang has the following words:
- dep = to move
- da = to (direction)
- xi = here
- mow = home
it would be possible to use "dep da xi" for "come here" and "dep da mow" for
"go home".

Are there natlangs which don't use different words for "go" and "come"?
