What benefits do you expect to see from the kinds astronomy that require this sort of funding? Sure, knowing things can be nice but this ignores opportunity costs, eg. would practical knowledge like fusion research be further along if talent weren't focused on impractical knowledge?

Not strictly true, see quantum computing for instance, lasers, semiconductors and so on. There are some types of physics that aren't viable in this sense, but why does that automatically translate into some need to support them? For instance, consider the decades spent on supersymmetry which ultimately produced bupkis. In a world in which we weren't so focused on ideas so divorced from empirical data, what other types of knowledge or engineering would we have done?

Untrue, Google and Facebook have advance distributed computing considerably, for instance.

Unclear, there's a lot of math involved in predictions of all sorts, like weather forecasting, stock market prediction. If your argument here is that math will be more application-focused, this strikes me much like the physics objection where it's unclear that we'd really be worse off.
There seems to be this automatic assumption among some people that pure research with no direction or constraints is an unmitigated good and that we can't do better. I used to think so too, but I just don't see it anymore.
