That doesn't sound scalable. Platforms like Hodlhodl, Peach and Robosats are kyc-free for me, and scalable. No service collects my data, only the counterparty has access to it. And if you use e.g. Revolut, the counterparty only sees a first name. But good luck advocating for in-person-bought-btc-only.

If you paid for the vouchers with CC, the voucher minter knows about you and can trace every voucher.
You are just adding an extra step.
