Good catch ! Looking at the code, it seems that this class was not touched for a while (created in 2007, last touched in 2009), so i guess nobody took care of it when the one() was created for all monoids (probably through the sategory mechanism). May i encourage you to open a ticket and fix it yourself ?

Actually, it is not correct to say that the monoid is not able to provide an identity element, you can get is as follows:

sage: b('')

sage: b('110') == b('') * b('110')
True
