Yes, of course. True randomness requires environment input. My point is that randomness you can use also requires trust, and trusting an opaque source doesn't cut the mustard. This is why using lava lamps to create random seeds makes so much sense - it's not just someone being cute. If I want to make a truly random seed today, I don't use my computer at all. I observe some external random event(s) and type in the results.
After seeding, I want my prng to be software, not hardware.
