Display and storage space is the real constraint once you have a few builds.
Following instructions is easy; designing original creations is a steep step up.

Model Railroading

Debugging one dead block for a whole evening would wear you out.
The appetite for table space, time, and money is too much.
Fiddling with tiny turnouts and ground foam holds no appeal.
