The big problem with one-time pads is distributing them. This problem still exists even with text messages.

There is no problem. You use a publicly available book. . . one that is the same regardless of where you look at it. There is just an agreed on schedule of when a specific book is the "one-time pad" being used. This can be as granular as down to a day, an hour, or even a specific time of day, just as long as sender and receiver (or their sending/receiving devices) know that schedule. Problem solved.

You're describing an effective encryption technique, but it's not the same as a one-time pad. I describe several of these fairly simple techniques in the chapter on encryption in my book RESISTANCE TO TYRANNY, including generation of one time pads from tables of statistical data (population, income, etc.) Like the book method, this avoids the need to physically distribute keys if the sender and recipient both have access to the same tables (edition of STATISTICAL ABSTRACT OF THE UNITED STATES, for instance).
