But, amateur radio isn't just about using crisp factory designed and built radios, it's for using home built stuff which isn't always as clean in the output as a five hundred quid Yaesu, Icom or whatever. If you keep your transmitted signal bandwidth to 12,5 kHz, then you won't be slurging onto the adjacent channels 25 kHz away.
