bc1 isn't an uncommon prefix, its a bech32 native segwit address that's been in use for years now (IIRC 1 and 3 are the other prefixes, 1 being the first and most popular and 3 being a backwards compatible segwit address, i.e. non native).

faulty key pairs being generated is a well known issue with poorly developed wallets, not with Bitcoin itself. None of the popular wallets have this issue so it doesn't undermine Bitcoin.
> the supposed point of crypto is to reducing the reliance on, and grifting from, companies like Coinbase
Yes, that is still the case? Decentralized exchanges like Uniswap are dominating (over $1B volumes daily) and growing very rapidly. Crypto is and always has been about decentralization.
Are you agreeing or disagreeing that it is a threat? Linux did take a ton of market share from Microsoft on the server side.
Linux is also not a good analogy IMO, because Uniswap has a lot of direct retail/consumer usage whereas Linux isnt used directly by the average person.
> people making investments with bitcoin backed loans
There already are Bitcoin backed loans offered by both decentralized services (like Aave, Compound, Maker etc) and centralized services (like BlockFi, Celsius etc). They get real usage. Aave, Compound and Maker have $17B worth of crypto deposited in them as collateral. BlockFi has a $2.85B valuation.
