The measurement problem is really a complex of problems, revolving around the question of whether one can apply quantum mechanics itself to the description of measurements. Intuitively, if the environment is carrying out lots of spontaneous measurements even without our intervention, then the measurement problem ought to apply more widely, also to these spontaneously occurring measurements.
Given that everyday macroscopic objects are particularly subject to decoherence interactions, this raises the question of whether quantum mechanics can account for the appearance of the everyday world even apart from the measurement problem.
The state of the object and the environment could be a superposition of zillions of very well localised terms, each with slightly different positions, and that are collectively spread over a macroscopic distance, even in the case of everyday objects
