Reason(s) for the current dust storm

Highly unlikely…
Cost of a fair sized farm vs cost of a new ssd.

The initial reason for XCH price to go up was purely a super hype. Those times are over now, and it looks like when the net space contracts, the XCH price also contracts to keep the market cap about the same. So, that would be a weak argument for me.

Although, (IMO) a big problem for chia is relatively high barrier of entry (e.g., crap software, long syncs, need to tune the node), and fast db growth is not helping here, as it further extends time to get fully synced. So, the impact most likely is there.

Therefore, I would look at that reason as an attack against Chia as a coin or company rather than potential goal of gains that can be made by whales through fees.
