PhD thesis without acknowledgements
A thesis is not a place to solve grudges. It is a professional document that is eternal. As such, it should be handled professionally and gracefully.

Still, I am having trouble why you do not want to have an acknowledgement section. Do you really believe you have done the entire PHD entirely yourself? Even if your advisor did not help enough, you had some funding right? And someone provided that. Should not he be included in the acknowledgement section? Someone also proofread your thesis. You probably also had co-authors in your papers. As you see, there are multiple people that contributed to your success. 

But on a more informal tone. Don't you wish to thank your family or significant other for the support? Or your PHD co-students? The people that you share your office with? You have finished a PHD and especially since it probably was a rocky one this a very good reason to celebrate. Do not spoil the moment with petty grudges. Do what you are required to do, be professional and move-on to better things.
