Don't tell them

As I see it there are many Bitcoin miners who can only sustain their operations because of fiat loans.

Running a business (especially a publicly traded one) enables a lot more access to debt. Funding what would otherwise be an unworkable business case.

I'm the long term there will only be two types of miners; those who have access to energy which would have been wasted otherwise (including some heat production applications), and people who do it as a hobby.

They're not dumb. So maybe ask yourself... What amI missing in my thinking? Why would they mine instead of just buying?

In my thinking... If you can mine your own transactions into the Bitcoin blockchain you're completely sovereign.
