You're assuming the consumption itself went up rather than paying more for the same stuff. And people are paying a bigger fraction of their incomes for these things. I don't know what this is adding to the discussion besides assuming away the problem, as if nothing ever becomes pointlessly expensive.
>Now, if you're saying separately that it would be great if we could legalize lower priced options, I agree with you. That would be great. But all that would do is make (preference-adjusted) consumption go up more, or perhaps make investment go up even more.
No, that's an assertion that assumes away one possible resolution: that pointless regulations mandate that only the expensive options be offered. It's unlikely, but your model seems to disallow the very existence of that dynamic.
