Taking on debt is MUCH faster and easier way for all shareholders in a startup to end up with $0.

Loans are a lot better when you're in a more stable scenario - lower growth and/or lower risk of implosion due to just being more established.

As well as Oxide is doing, startups are still volatile and taking on debt that might need to restructure or be defaulted can create a lot worse outcome for shareholders than just "we diluted and then stopped growing as much".

depends on market conditions and visibility on future revenue. And current balance sheet, cost of debt vs cost of equity.

Not necessarily, no. That’s just one option with its own risks and tradeoff
