I'm not sure that is healthy, not for undergraduates. I'm all for open access to knowledge, but I question how much knowledge is actually in the average undergraduate thesis. I think a greater danger exists in people being held to things they said while an undergraduate student.
Famously, some of the stuff written by president Obama while he was a law student at Harvard has not been released, nor should it be. We shouldn't hold people for a lifetime to the incorrect, dangerous, or just outright silly stuff they might have said in a papers when they are new to a subject. Putting undergrad work into a perpetual public archive would also have a chilling effect amongst young students who should be enjoying academic freedom. I cannot remember 99% of the stuff I wrote as an undergraduate, but I know that somewhere in there is something horrible that I am glad to have forgotten.
My bachelor's thesis was pretty terrible and there probably is not much to learn from it for an expert. It would have been helpful to me to read other peoples thesis when I was a student though and maybe that would have led to a better outcome.
At least here in Germany, a lot of the funding to do the research comes from the government. As a tax payer, I'd like to be able to know the outcome of the research. I am sure there are some real gems in there too.
If a student has reasonable concerns, I would be fine with it not getting published. I believe that the default should be that it gets published.

I can't believe I have to say this, but not every university is UC-Berkeley. Digitization isn't free and requires specialized labor and technology.
And are you really saying that in the late 1980s, all dissertations were submitted digitally? In what format?
