> why is the partnership with the two huge banks necessary?
The banks are providing: 1) cash 2) loan origination and servicing.
Tesla doesn't have a cool $1B in cash laying around to make 15,000 car loans. The banks do as they lend from customer deposits. Tesla needs the cash immediately to buy more parts / pay employees.
Also, Tesla doesn't have a team of people that know how to review and check credit. Nor do they have call centers to remind people to make their payments, and if they can't arrange a repossession.

Tesla doesn't need the cash in reserve to make loans to buy Tesla cars; such a "loan" in that case would simply mean "not requiring (immediate) payment". It certainly means forgoing some liquidity, but that's not the same as them having to come up with the purchase price for all their cars; they're paying themselves anyway.
