Help answer my Dad: What backs Bitcoin?

Hey Guys, I’ve recently listened to Safidean Ammous on Lex Friedman’s podcast and I honestly can’t tell you the last time something has made so much sense to me. Since then I have started to read the Bitcoin Standard and it really does resonate with me. Since, I have desperately been trying to get my dad to at least listen to the podcast, because I know for a fact, as he listens to that or reads the Bitcoin Standard he will buy tons of BTC.

So firstly, do you guys have a suggestion of how to get him to take the time to listen and read.

Secondly, he asked me what backs Bitcoin as opposed to gold. My understanding is that gold’s value is somewhat proportional to the cost of which it takes to make it, and then it’s scarcity. Similarly to Bitcoin, it reckons energy & compute to mine, so cost of production in that sense and that gives Bitcoin its value along with its scarcity? Am I getting this right?

Thanks
