∴, Bitcoin is immune to capitalism and usury.
1. Getting interest on loans is perfectly normal, those who lend money are locking themselves out of spending their money for a long time + they risk losing those money, while those who take loans gain access to money they otherwise wouldn't have.
2. Capitalism is not usury, capitalism is freedom to do with your property whatever you want.
3. When it comes to Bitcoin loans, people generally demand a collateral and punish those who default on loans with red trust on this forum. In real life collectors could be employed to collect loans just like they do with fiat. If Bitcoin will get more widely adopted, Bitcoin banks will start becoming a thing, want it or not.
