Inefficiency and effort involved. 1. Encoding and decoding the data takes time and code. 2. The encoding expands binary by 4/3 (three bytes are encoded into four) 3. Duplication - e.g. if the same image is included in N places it will (likely) get encoded and stored N times, costing time (encode/decode) and space. Like everything, it is a trade-off.
