My perspective would be that a government providing services like healthcare which is funded via taxation is not communist in any way. It’s just called government.
Maybe in a shithole where your government just taxes you and then you still fork out for healthcare, it might look like communism… But most people would just call it public services.
You can test for mold using an air quality monitor that has a PM1.0. That means it detects particles <1 μm in size which is good for bacteria. Combine that with an air purifier suitable for the size of the cellar.
Windows to cellars should already have trickle vents otherwise it could get damp pretty quickly. Look carefully at the frame of the small window. If no trickle vent, look to install one.
