I think the issue is that people are using DAI to leverage what is an "investment" (or gambling, depending on your perspective) in ETH. But this isn't a failing of DAI. DAI merely allows you to leverage an existing position in ETH into a higher risk / higher reward investment, the DeFi way. This is only one of DAI's use-cases.
That's probably not a good idea given how risky ETH is on its own, but again, it is not a unique failing of DAI when people use it in very risky ways. For example, you could take out a personal loan to achieve the same level of financial irresponsibility (as many people did when they used their student loans or whatever to buy crypto).
