It's not so much a show off lapis. As it is a show of effort/work. That's the center for minecraft, showing off effort and work.
I will argue that a good portion of the showing off isn't necessarily tied to mining the materials themselves. That's just a grind and adds sentimental value to the creation. It is the time and effort put into painstakingly designing your creations, picking what material would look good in certain spots, making the place have complex redstone mechanisms yet still look nice, etc.
Basically, I'm arguing that it is the act of building that adds the most value to things in Minecraft. It's why people fawn over things built with Creative mode like what the RPGmakers (Jesse Cox and the whole Shaboozey gang) make. The blocks themselves add some value but it is the aesthetics and complexity of the build that adds the majority of the value.
Anyways, speaking from personal experience, building with wool wasn't really worth it before sheep could regrow it. I know I never bothered with wool before, partly due to my preference towards buildings built with materials that would be stable in reality, but now that I get a better return with wool (with regards to time spent gathering it) I might decide to use it in something.
