No but it isn't wise to generalise two of Europe's less... regulated countries to just "Europe". Pretty much every European country north of the Alps and west of the Vistula have mandatory smoke alarms/fire detection.

Oh and by the way, "just stay home" is pretty shitty as a solution even in itself because taking years off work is significantly damaging to one's career and women are disproportionately expected and pressured to be the ones to do so.
