This question stems from the earlier conversation on transporter access and who could use it and how.
Since we seems to be in a "fleet bubble" - that is, seeing a good deal of Starfleet/other military agencies' technology and access to it, we tend to assume (subconsiously) everyone has the same level of access to what is deemed "basic" tech - tricorders, transporters, etc.
But do they really? Do most civilians we see only have access due to being aboard the Enterprise-D and therefore surrounded by tech or those who use it as part of their job? Does everybody on Earth have a tricorder the way most/many now have cell phones?
