Your argument (that it is not much of a barrier to use the old way) can be made for so many of the quality of life improvements we have made over the course of human history. Not every advancement is an entire new category of things we can accomplish; so much is just slight improvements that save time and make things a bit easier.
I feel like there has been a backlash against time saving tech, where people wax nostalgic about how much better the older/slower systems were. I don't understand it. I am so happy for all the timesaving advancements we have made over the years. Now, if we don't use that saved time wisely, that is a whole other issue. However, I don't think going back to slower systems is the solution to not using our free time well.
