For some games, like Minecraft (redstone) and Factorio (logic gates) it's easy, but for others it's difficult enough that you get to see some creativity. This is one of those latter instances.
So it's the worst of both worlds -- an expensive simulator for tediously manipulting low-level primitives. Why not manipulate primivitives efficiently, or use high-level constructs?
Then serious Minecraft constructors build mods and tools to automate the tedium back out anyway, so they design whatever nice things using high level tools, but then execute and inspect the builds on inefficient computing systems of cryptocurrency-level of wastefulness.
Why not just make whatever thing you want out of good (virtual or physical) materials in the first place, and then put it under the microscope/oscilloscop/decompiler/hex-editor to marvel at its complex structure?
