Of the 15 or 20 business owners in the room, I was the only "pro privacy" voice. People were very focused on what would be the perceived additional cost of complying with any GDPR-style rules in the US, and weren't yet thinking about the negative effects of having different privacy rules in different markets. "Different markets have different rules all the time," in short.
I maintain that it would be less complicated, less expensive, and more human-friendly to use data privacy rules as globally universal as can be achieved. There will always be capitalism leeches that drain money through arbitrage between the policy gaps, yes, but it would help.
(Also: there is zero chance this gets through the current US Senate. Would never clear filibuster.)
