Focusing on the well-being of who that number represents or doing what benefits who that number represents, that's a reasonable interpretation of how it could work without a literal physical mark, sure. But in context of the verses around it, I'd still say it's more likely about doing things beneficial to the Antichrist rather than just self-interest.
