I know that Collider Machines require a Collision 2D component to work, however if I simply want to activate a schematic by having a player walk onto an area, with no collider to impede the player's progress, what's the simplest way to achieve this?

Usually for something like this you'd use a Trigger Machine that starts when the player enters the trigger (i.e. collider with Is Trigger enabled).
The only alternative is having e.g. a Tick Machine constantly run and check the distance to the player before doing whatever you want to do.
