I'll grant you that it's more important to have a password be difficult to guess, but that doesn't obviate the importance of it also being easy to remember. Even better, let's look for password schemes that are harder to guess and easier to remember at the same time.
It's easy to compare the entropy of two schemes as you're doing in your comment, but it's more difficult to objectively claim which is easier to remember. You argue that a random sequence of 12 characters is easier to remember than 4 words. If so, then I'd agree it would be a better scheme. However, I don't think that's the case. To really settle the argument, we should do some experiments - maybe someone already has?
Here's some examples I used a generator to create:
