Look at it this way:

You have around $15 EV in this tourney right now. Pushing is probably worth about 15 cents right now.

If you make it to the bubble you may have $25-$30 EV in the tourney. You may have several opportunities to push worth 30 cents or more each. However, these opportunities only arise when you can put your opponents on an accurate hand range.(preferably as tight as possible)

The more confidence you have in their calling ranges the more profitable spots you are going to find.

Can you see how raising here damages you by hurting your ability to put your opponents on accurate ranges and make better decisions in the future?

Well said. I don't know how much image matters at the $22s, I just don't have enough experience. But I know that even the biggest of donks notices when you push 10xBB from the SB into his BB. Could induce a call later when you don't really want it.
