Which licenses would that be? I understand that this pulls extra legal and commercial obligations but it's not clear that this requires a license.

For instance, this does not seem to be an e-money activity. I know Stripe's pitch for Connect says that they have an e-money license (and money transmitter licenses in the US but let's focus on Europe), but to me that does not imply that an e-money license is required for a marketplace.

Edit: Ah, the licensing requirements seem to stem from PSD2.

The problem with Stripe Connect is that unless you have volumes to negotiate the standard fees are very high. And of course those regulations effectively mean that they own your business...
