Aller là-bas

Question

Two Kwiz questions linked to this lesson give the above construction for "go there" - can y aller be used instead? Is there a distinction?

She wants you to go there = Elle veut que tu ailles là-bas

Do you want me to go there? = Veux-tu que j’aille là-bas ?

Bonjour Anne,
If you don't know where 'there' is, you have to use 'là-bas'.
The pronoun 'y' normally replaces a place previously named.
Although sometimes it is used in idiomatic expressions like -
Vas-y ! = Go ahead! Go on! (and do it) 
Bonne Continuation !

Thanks. I thought both English phrases suggest we do know where "there" is, if talking literally. Figuratively is different, as in "don’t go there!" but really that’d only apply to the second example, it doesn’t make any sense for "She wants you to go there".
