Earlier quoted context omitted.
I think this is the core issue for me in these discussion - it is not complex at all. If you sell your securities - you pay a tax - that part is simple. Until they it is "unrealized" - right? > If you write a covered call, did you "use" the asset? Yes > If your broker lends your shares out, are they being used? Yes > What about presenting your brokerage statement as proof of assets to a mortgage banker? Of course not…
> What about--I've done this--showing your brokerage statements to American Express to get a better rate? Of course not You say "there is nothing complex about this" after conceding this loophole the size of a planet. For starters: loan with a covenant that governs further borrowing and requires you to instruct the lender if your marketable assets fall below a certain value. Not technically secured. But not relevant…
You did not say anything like this, you said "What about presenting your brokerage statement as proof of assets to a mortgage banker?" - this is like me showing my bank account balance during speed dating to flex a bit :) Your example would be 1000000% taxed as you are obviously using it as realized gain.
> Next up: loan to heirs.
If you are using real money, loan all you want. If you are using "money" you are telling Uncle Sam you do not have then you pay tax before you borrow that.
> Next up: unsecured loans at preferential rates if you store your securities with the lender. (This is already a thing.)
This is up to the lender... If they want to use my skin color or my gender or my zipcode (all of which they do) they can also use other stuff as well
I get that I am oversimplifying this but surely a system can be put into place that prevents current madness :)
