That's an interesting point.  In the US, around me, there really aren't
such assumptions.  Instead, a lot (area of land that can be bought and
sold as a unit) has an address, generally taken from a public or private
way that borders the lot.  Some lots don't really have addresses that
are useful, if they aren't near roads.  Then a building on the lot,
certainly if there's only one, inherits the address of the lot.  ANd if
there's going to be a building, then the lot needs to have a proper
address (for emergency services purposes) and one will get assigned.  So
it definitely tends to work out 99.99% of the time that a building's
address is near the named road, and that one drives to that road to
access the building, but it's not strictly by design.  In confusing
cases new addresses tend to get made up, usually by granting the (new)
access road a proper legal name, so it that sense what you said
describes how we do it.    That's a long way of saying that it's messy
and that general rules don't always hold (in mass.us; not saying that
applies to .fi).

This is quite separate from access.  There are addresses on military
cases, and very often in residential complexes with gates that you need
a code/etc. to get through.   So it's not just access=destination but
access=private, and yet they are real addresses on named roads inside
the gate.
