To answer the question - no.
Would I like to be able to have just one? Not sure.
If I were in a band where the genre/songs and band composition were able to be covered by just one bass, then it’d be viable, although that does leave you open to gear failure, with no backup (I know some folk do this and I have myself, but it’s a risk).
I think it’s worthwhile having one bass that you really know very well, your go to. However, knowing that bass throughout should also make you aware of its limitations and this is where others that fill that gap come in (fretless for instance).
All the above should also be studiously ignored as, since moving 500+ miles, I have no band, no prospects and 5 basses not doing a whole lot at all (I’ve even bought 2 since the move - I need help) other than playing for my own pleasure.
