I know they can easily verify it by checking flights, and my expenditures.. but how do they find out in first place, if nobody submits a request to verify?
For example: I’m resident in France, and I spend more than 6 months in Spain.

Edited in response to the comments: There are different laws this idea might break, and different ways how this might come to light. Or not -- making it easier to break the law is a consequence of making legitimate border crossings easier.
If the authorities start to suspect you of tax evasion, that crime may be investigated by more or less intrusive methods. It is a crime, and the police have various means at their disposal. And if you are caught, a low-probability event, the consequences may be dire.
As pointed out already, it depends on several things. But since you mentioned Spain, landlords there are also expected to pay taxes. If they comply, that may expose you. And if they don’t, they are cheaters, and will likely also try to cheat tenants. Which will eventually result in a cheated tenant reporting them to Hacienda, resulting in an investigation that will probably expose you.
