Eventually, those large crops might get to the point where they have to declare bankruptcy, while they might still function as per your explanation, good luck finding anyone to invest their money with large mining crops.
We have something close in the EU
If a company goes bankrupt you can appoint a judicial overseer that will consult with the debtors and if the company without servicing the debt is capable of staying afloat in most cases it will rule against liquidation, and it will grant 12 months increments periods in which the company is protected from any debt related cases. The more people they have employed the easier it gets, I know a case of small chain stores that had over 1000 employees and they got like that without paying their debt for 5 years, fortunately, that was a happy case, they've managed to recover and actually pay the settlements.
So if you think of Mara or Riot going under, after the second halving maybe

And finally, we're going down a bit although I'm pretty sure it will change drastically pretty soon
Latest Block: 736571 (25 minutes ago)
Current Pace: 97.5315% (732 / 750.53 expected, 18.53 behind)
Next Difficulty Change: between -2.4631% and -1.4787%
We're behind 18 blocks, but in the last 24 hours, we had only 130 mined, so that's where 14 come from, if it weren't for the previous day we would be at 99% so this could turn positive in just a few days. As for the price, I don't see that breakthrough, not this month unless something big happens. People trolling the %^%$ out of Twitter and Reddit about hundreds of suicides caused by terra and just are not helping at all.
