If you check hourly RH changes you will find that it can vary by 50% points or more within a 24 hour period, and often does. Guitars survived for over a hundred years before central air and humidity control existed.
Because makers are building lightly built "responsive" guitars from less than well aged materials humidity control has become more of a concern. Another problem is with the modern heating of houses in the winter to warmer levels than formerly the RH can drop into the teens or single digits unless supplemental humidity is added.
Still, guitars should be able to handle RH levels from 30 to 80 percent without a problem, so ultra tight control of RH should not be a concern for the average owner.
Excellent post on the subject and it falls in line with my experience.

Best,
