I believe the answer is:

go without

I'm a little stuck... Click here to teach me more about this clue!

'don't have' is the definition.
The definition and answer can be both to do with ownership as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?

'leave the building' is the wordplay.
'leave' becomes 'go'.
'the building' becomes 'without' (I am not sure about this - if you are sure you should believe this answer much more).
'go'+'without'='GO WITHOUT'

'to' is the link.

Can you help me to learn more?

(Other definitions for go without that I've seen before include "Suffer a lack of" , "Want" , "give up" , "pass up" , "be denied" .)
