Now you have e.g. a data breach, or your entire inventory goes down in a flood/fire/accident and you're not properly insured (most private insurances will not cover your business assets, even if your business is in your home), you're out of luck.
And as we're speaking of capital: in the Valley, you basically have to have a good business plan, a sales pitch and a bit of luck and you'll be bathed in cash (at least, this is my impression of reading here). In Germany, no luck obtaining a larger credit or startup financing as long as you don't put up your house or car as collateral.
