Every business need not be "the solution" to a problem. Problems can often be solved in multiple ways.

Getting from origin to destination can be done via horses and also via automobiles. Whether they realized it or not, Ford's customers were looking for faster travel, not "faster horses".

A business only needs to be an attractive (alternative) solution to a problem; it must be as or more attractive than the others.

Great point--doesn't necessarily have to be an original problem you're solving, nor does it need to be the ONLY way to solve the problem you're addressing.
