Would you not accrue more Bitcoin in the long term if you did not get a BTC backed loan but instead sold your Bitcoin to eliminate debt and bought more Bitcoin with the freed up funds?
Yes, your stack takes a hit in the short term but over time you acquire more than you would have since a BTC backed loan does not increase the amount of bitcoin you have.
I understand your point of appreciation but physically stacking with freed up money no longer going to debt may earn you more Bitcoin in the long run.
