Fingerboard wear, like fret wear, is reality for all stringed instruments. Both can and are remedied when necessary during the life of the part. When the situation becomes critical the part can be replaced.
The question you should ask your self is "What is more important, preserving the condition of the instrument or tone?" Then make your choice.
My personal, unvarnished opinion is that musical instruments are for playing. The choices we make concerning the instruments are for tone.
If instrument preservation is the most important thing on someone's list they should become dealers, techs, or museum conservators rather than musicians.
