Can we take Mavis surprise about Jacob being able to hit her to mean that she can't directly interact with matter (i.e. can not touch anything)?

She thought "my body, which has no physical form" on MS or "I don't even have a body" on MP. Does that mean it never has a physical form all the time, or is that something she can change about this astral body, like Jellal who was able to modify his thought projection to become able to touch others?

Maybe someone taking a look at the raws to tell us exactly what Mavis thoughts were might help here, to see if something was lost/changed in the translation.

So far we've only ever seen her touch things and drink in OVAs, where they tend to just mess around for a bit of fun, while ignoring some of the finer rules.
