I think you are coming from a common perspective for people on HN and elsewhere in IT, where you can just install anything and provision any equipment to install it on and direct others to do the same. A lot of people aren't in a position to do this. I think actual plumbers also have to deal with similar constraints. It's nice to not be constrained, but it's also more impressive to do a good job under severe constraints, IMO.
