Even with a tight constellation of 500,000 to 1,000,000 satellites packed into that band, it still doesn't make economic sense compared to what terrestrial data centers can do. At 500,000 satellites you're looking at maybe 50 GW of solar power. Then factor in the lifespan of LEO at ~5 years you're looking at hundreds of satellite launches daily to maintain that infrastructure.
Now work is being done for increasing solar access (Starcatcher) and others are working on improving LEO refueling and repair capabilities, but I would say we're decade+ away from establishing any true compute infrastructure in orbit.
decade+ is not really that long, is it? Say you're correct in that time frame. If you put money in now to a venture that seems uncertain then in 5 years it's going to seem much less uncertain - and so the investment will be worth that much more.
I think there's an oft repeated view that markets only look to the next quarter. That's not really true. Markets (or people) are willing to go in on long term investments as long as they believe they understand the uncertainty. Which leads to crazy 2nd and 3rd order speculation (I think you think that they think...)
Personally putting money into space based datacenters seems crazy to me currently but in a couple of years it'll be more clear as to just how crazy this is. At which point the opportunity (and risk) will be gone one way or the other.
