After a bit of digging, it turned out that the authorization is demanded on this step:

        to_assets.emplace(asset_itr->ram_payer, [&](auto &_asset) {
            _asset.asset_id = asset_itr->asset_id;
            _asset.collection_name = asset_itr->collection_name;
            _asset.schema_name = asset_itr->schema_name;
            _asset.template_id = asset_itr->template_id;
            _asset.ram_payer = asset_itr->ram_payer;
            _asset.backed_tokens = asset_itr->backed_tokens;
            _asset.immutable_serialized_data = asset_itr->immutable_serialized_data;
            _asset.mutable_serialized_data = asset_itr->mutable_serialized_data;
        });

assetitr->ram_payer is the account that minted the asset, and its authorization is required for each transfer on my local blockchain. Obviously, this does not happen on the main chain. Why? What's the difference? How to set up a local blockchain so it behaves the same as the main one?
