Walter,

The problem I see is that certain people keep saying everything can be done in NET so there isn't a problem. Issues like efficiency or appropriateness are completely ignored. It's as if somebody has decided that walking is always best. If you point out that to cross the USA you'd prefer to drive or fly, you are lectured that most people don't need to move across the USA so it's not relevant. In any case, it is possible to walk across the USA so there is no advantage to driving or flying. What about schedules or the need to carry heavy materials? There you go again, picking out minor issues to try to justify your ignorant bias. Those who are capable of thinking are well aware that there is a quick form of walking called "running" and I might have guessed that a dumbo like you has never heard of a wheelbarrow. Followed by the suggestion that those opposed to walking (when did anybody become opposed?!) haven't investigated for themselves, which is why they have no idea what they're missing out on.
