I think we need to decide, if unrealized gains are real gains. How you can loan using unrealized gains as collateral if from tax purposes it’s not real money.

If you can loan money using unrealized gains a collateral you should be taxed. I am not saying you tax unrealized gains, but taxing when get money “from” it.

But loan is considered a loss and you even get a tax break.

Also need to limit tax write-offs to really business needs, like rich people can get a huge car like a Mercedes G class on their business and write-off the cost for instance. The rich have a lot of loopholes. Incentives should be limited to people and companies making a X sum. If your company makes billions, I don’t think you need a tax incentive.
