Very interesting post @rok-sivante, you made some great points. Honestly, I would not have the knowledge to comment a lot on this, apart from the integration with a hardware wallet.
If integrating with a hardware wallet, the main issue that I see is getting the wallets to be compliant with Bitshares. If they are, then $70k should not be a problem, but I just think that if it was that simple, a lot of cryptocurrencies would do this as their inherint price should go up, based on the amount of new users they would get. I'm not sure how one would go about this, but I'm going to look into it further. Thanks for sharing!
