Or to put it another way, the things we're regulating as a society should be an individual's ability to cause harm to others (either intentionally or unintentionally), as that deprives others of their freedom to live their own lives.

If an individual is endangering only themselves in a way that poses no risk to others (e.g. blowing up stumps on their own large property), then that's a responsibility they should be given.

Which does suggest stricter limits on higher density areas (read: cities), given the proximity of people and lack of empty, fuck-around space.
