Yes, hashing is expensive, and mining is expensive.
It's important to note that all this is because mining is valuable. Just one PC would be enough to process all Bitcoin transactions (at very low difficulty). It's the competition for blocks that increased the hashrate, and it's only limited by how profitable each block is.

You think only about short-term profits. Many miners are not like that. To make sure, that their blocks are valid, mining pools often are running full archival nodes, especially if they are handling a lot of coins. And then, the bigger the block size is, the worse for them, because it takes more space, and it gives less fees. So, mining pools have an incentive, to keep blocks small, because then, it is easier to run nodes, and it is more expensive to transact, so they can get more fees out of it.
Miners turn over $50 million per day, while $100 is enough to store the full blockchain on a fast SSD. I can think of many reasons to limit blockchain growth, but mining pools' storage requirement isn't on that list.

I thought for a while, that sweeping dust is non-standard. But it seems only sending is, and sweeping can be done normally.
From a spam-perspective that makes sense: cleaning up UXTOs shouldn't be restricted.
