Pure oxygen interacts with all sorts of things and fire can result. Example: Pure oxygen and hydrocarbon materials like grease = instant fire. You're also dealing with high pressures and connections between tanks and filling equipment. Not for the casual user. Tank filling oxygen generators are also very expensive.
