There are ways to "shield" much, but this is complex enough that you should consult an attorney to sort you precisely WHAT you wish to accomplish and the best approach to getting CLOSE. You will not achieve the anonymity you speak of here, but you might have one or more credit cards, and/or bank accounts (for example) where the D/B/A name functions well. The bank, of course, must have and know YOU, because you must use a social security number or tax id number for tax purposes, etc. Lots going on here.
