The textbook interpretation is that all of Maxwell's equations are 
valid anywhere in space whether any conductors are present or not.

Again, if you don't believe in displacement current, you still have 
to explain how electrostatic forces can do mechanical work. If you 
agree that there can be no electrical power without voltage and 
current being present at once, then you must admit that there can be 
no mechanical work without E x H. So if you are able to move a 
non-conducting object using an electrostatic field, displacement 
current must exist. That is my argument and I'm still waiting to see 
a counter argument.

Explain how the balloon pulls up to the ceiling and sticks to it 
after rubbing on the cat, then. If mechanical work was performed, 
there must be both E and H fields present, and the only thing that 
could have created the H is displacement current since there are no 
conductors present to carry conduction current.
