(1) Our tax structure isn't going to change meaningfully anytime soon
(2) The IRS won't allow or enforce any sort of efile for everyone in the short-term
(3) The IRS does allow you to file Form 14039 which puts a flag on your account which will make it harder for someone to cheat you out of your refund because your account will go through extra checks (such as making sure that your address and other information hasn't changed from last year since most information breaches don't contain all of the information necessary to file your tax return) and will reject fraudulent looking returns

(4) The IRS might decide to, upon filing form 14039 or if you have experienced a fraudulent return filed for you, a distinct PIN which is like a PIN for a credit freeze
Morale of the story if you're concerned about not getting your refund
-file form 8822 when you change address and notify your employees and other agencies which file forms on your behalf to have your current address so all filings point to the same physical address
-file form 14039 to have the identify theft flag added to your profile
-always try to arrange so you owe a little money come tax time (but not so much that you owe a penalty) so your refund is not in purgatory in the event of a fraudulent return filed on your behalf
-if you do indeed get a refund, try to file as early as possible to beat out a fraudster
