If there's a single rule for small business it's "Cash is King". Cashflow is what kills you and the monthly income statement is way more important than your balance sheet.
This is actually why the balance sheet is more important than the income statement. The income statement can obfuscate what's happening to cash flow. A close study of the balance sheet reveals whether working capital is consuming retained earnings.
I figured the idea of labeling the inventory as an asset was part of the practice of later deducting the cost (expensing). I.e. you can’t expense it twice.
I'm assuming this was slightly in jest, but paying yourself is all about free cash flow when you're bootstrapped, fronting inventory and growing. And in practice, with hard goods this is really difficult unless your gross margins are really high.
