The simple reason is that least reactive elements are mostly found in their native state while reactive elements are found in combined state (in form of their compounds). It is easier to extract any element in it's native or elementary form. Such elements can be easily separated from their ore. They are separated by using physical processes. Reactive elements need to be extracted from their minerals through chemical processes which are more expensive and tedious.
NO Gold and platinum are not revy reactive.
Generally, the least reactive elements are the noble gases.
Noble gases are least reactive because they have a full shell
magnesium (Mg)
The noble gases are the least reactive among all chemical elements.
