The non KYC part either way is quite relevant, non KYC means that Pocket will not hold any photos of you and your passport or ID, nor your home address in their servers, that is already a big plus. Add to that is self custody from the getgo and it is even better.q

To buy and sell Bitcoin you will provide a Bank account, many banks in Europe are Bitcoin friendly (the irony, some things really change), every country with their own, and some internet base like WISE and Revolut are decent options, none is perfect, dealing with banks is never pleasant...

And I agree, buying Bitcoin not p2p with options like Robosats or Bisq or directly from miners (my favorite) is not flying under the radar as you well put it, but most people don't care about that, they trust banks and they want to buy Bitcoin, so this is a good option for them, all Pocket will have is their bank account details, which is miles better than conventional KYC.

Soon conventional banks will offer Bitcoin ETFs and soon after spot Bitcoin and they will custody it for their customers, those barriers may soon be erased completely either way, unless... Regulation in EU becomes tyrannical and only KYC Bitcoin is allowed and self custody wallets are banned, seems unlikely at this point but after so many years of battles and the well known incompetence of the EU leaders, nothing surprises me any more...
