It's not about the energy for me. A lot of these posts make networking and homelabs seem like a dark art that only folks with tons of space, capital, and time can get into. Networking is anything but, it's about sending a packet of data over a wire! But when we glorify these elaborate, expensive setups, we not only lose focus on what the goal of a network should be (to satisfy needs for its users), we also discourage newcomers from tinkering with networks which to me is the bigger crime.
