I trust that you won't be surprised to find that I agree with both of these, without qualification.
So why give the following advice?

Because it raises awareness that can help lead to change in the field. If one student walks into a beginning Greek class and after some time asks the professor why they aren't using Greek in class, the professor is likely to brush this question off. But if two students do this, it may get the professor to thinking unsanctioned thoughts. "Why aren't we doing that?" And imagine if a whole group of students were marching into a shrink's office singing the Alice's Restaurant massacre in four-part harmony? (Younger listers will need to listen to Arlo Guthrie's Alice's Restaurant to make sense of this reference.) I think that every student should be told at the beginning of their training that oral use of the language for real communication is vital for the most rapid progress in the language. Eventually, things will change and this will be good for the field.
In the meantime, by all means, start learning Greek.
