Not at all. Mold doesn't only damage the floor but also becomes the reason for being sick. Mold is very unhygienic. You will get immediately ill if you have asthma or allergies.
Don't think you don't have allergies or asthma problems, so you are saved; it won't cause you. Mold exposure will create irritation on your skin, eyes, nose, throat, and even lungs.
So not because to keep your home fresh and beautiful but also to be safe from problems mold creates, you have to get rid of a mold problem as soon as you can.
