I'll be the dissenting voice. Imagine that you work for my company and that, rather than the CEO, we're carrying around a real estate team today. We have two problems. Number one, there are people in the community we are looking at who may not be real happy that we are thinking of building there. Number two, we have competitors who might be very interested in where we are looking to build.
Without blocking we might show up to the airport to find an angry mob of villagers with pitchforks and torches. Or, worse yet (?), our competitors there already closing the deal on the same parcel.
It's not ALWAYS the fat cats heading to Aspen guys. There are legitimate business reasons for privacy.
^^This^^ X 2.
Also, many of our business clientele work for private corporations, not publicly traded entities.
