I concur with Tuuvi. I'm the worst kind of engineer, the one that enjoys neither math nor physics, but the specific mods I mentioned means that it won't matter. If I put in enough effort into strengthening my infrastructure, I can build all of the things I've always wanted to without cheapening it by giving myself the blocks for free. The ceiling for improvement is put extremely high in doing so.

And, if, say, TC wants to build another glorious palace of Nether Quartz, he doesn't need dozens of man-hours (his or others) spent mining and mining and mining. He could plan it and place it, spending more time on aesthetics and design.
