You can simplify this even more. Open an InteractiveBrokers margin account and request a debit card. Fund the account, purchase gold (futures, GLD, whatever) and spend on your IBKR debit card. This will pull from your margin. Your margin interest is ~1% and tax deductible. Settle up your account as you see fit.
I use IBKR margin, but didn't realize it was tax deductible!? Thanks for the tip!
Yes, you can use it to offset capital gains. Also, depending on your largesse, consider tax-aware borrowing. [1]
