True. "Pure" randomness will always be preferred to provide a maximum security.
If you need a key that you feel could keep your data encrypted for 50 years, geokeys would not be a good choice.
However if it is short term use like with bitcoin you can do a trade of between level of key security and risk of losing the key.
You would not have to make sure the encryption lasts for 50 years but only as long as you want to keep this key.
