The problem with this argument is that you couldn't have borrowed that much money from a bank in 2011 to buy Bitcoin. Even if you could've you'd still need to live somewhere and pay back the loan. It's not realistic to think that way.

The real value of a home is that a bank will give you a loan to buy it. This leverage shouldn't be underestimated. Yes, it comes with taxes and other downsides but it also gives you somewhere to live and build equity while you accumulate Bitcoin.

So realistically, the best strategy, with the benefit of hindsight would've been to buy a house AND start accumulating Bitcoin as savings. Not so different to now.
