I guess it depends how you view your obligations. If you don't want people to be able to read, vet, or reproduce your research because the citations are suspiciously tricky to follow up on, that is of course your prerogative. As a scientist free and fair access to accurate and easily verifiable information should, of course, be in the forefront of what you care about. It is completely doable as well -- I've done it with my research for years. Even when citing books, I always ensure the relevant passages are available in Google Book search or something like SciHub. If not, I won't cite that source, because I wouldn't have been able to access it in the first place anyway.
