Just because you cannot see someone, does not mean they are not there.
The naive thinking displayed here is not new. When I conducted research for my dissertation in the late 1990s, I looked at the use of the Internet by SMEs, comparing UK and German companies. One common finding was that in both countries, companies recognised the new markets that the Internet was going to open up to them (e.g. outside of their current market geography), but failed to see that there would be increased competition from other companies they previously didn't contend with.
This surprised me as it was completely irrational.
So it is here. The Internet provides greater opportunity to work flexibly (completely independent of physical location), but people don't understand that it means that someone in some random country or location can access their services just as conveniently as they do.
