Current Sheets, Plasmoids and Flux Ropes in the Heliosphere
So your assertion based of a 1938 paper is not correct, unsurprisingly!
So, let's first have a look at the list of authors for that paper;
O. Pezzi, F. Pecora, J. le Roux, N. E. Engelbrecht, A. Greco, S. Servidio, H. V. Malova, O. V. Khabarova, O. Malandraki, R. Bruno, W. H. Matthaeus, G. Li, L. M. Zelenyi, R. A. Kislov, V. N. Obridko & V. D. Kuznetsov
We'll come back to a few of them.
Let's also look at some of the papers referenced in that paper;
F.V. Coroniti, On the tearing mode in
quasi-neutral sheets. J. Geophys. Res. 85(A12), 6719–6728 (1980)
P.L. Pritchett, F.V. Coroniti, V.K. Decyk, Three-dimensional stability of thin
quasi-neutral current sheets. J. Geophys. Res. 101(A12), 27413–27430 (1996)
M.I. Sitnov, H.V. Malova, A.T.Y. Lui,
Quasi-neutral sheet tearing instability induced by electron preferential acceleration from stochasticity. J. Geophys. Res. 102(A1), 163–174 (1997) (I believe the latter author is known to Tusenfem. The second author is a co-author on the paper Sol88 linked!)
Back to the authors of this paper that Sol, for reasons known only to himself, thinks contradicts Alfven's claim that the solar wind has to be net neutral;
Let's just concentrate on the lead author and a couple of others, whose papers I have already dealt with on here;
O. Pezzi, H. V. Malova, & O. V. Khabarova.
(Bolded authors are co-authors of the Pezzi, et al paper linked by Sol.)
Differential kinetic dynamics and heating of ions in the turbulent solar wind

O Pezzi,
S Servidio, R De Marco, F Marcucci,
R Bruno, B Lavraud, J De Keyser, G Consolini, D Brienza, L Sorriso-Valvo, A Retinò, A Vaivads, M Salatti and P Veltri
Valentini said:
In this model...The displacement current is neglected and quasi-neutrality is assumed.
Multilayered structure of thin current sheets: multiscale ”Matreshka” model
A. S. Sharma,
L. M. Zelenyi, H. V. Malova, V. Yu. Popov, & D. C. Delcourt
Sharma said:
The electrons are considered magnetized with finite inertia across the field lines and negligible inertia for field-aligned motion. The resulting charge separation generates an ambipolar electric field Ez supporting the quasi-neutrality of the plasma.
Universal Scaling of Thin Current Sheets
L. M. Zelenyi, H. V. Malova, E. E. Grigorenko, V. Yu Popov,
and E. M. Dubinin
Zelenyi said:
...due to plasma quasi‐neutrality ion and electron densities are almost equal: ni = ne ~ n;

Khabarova, O. V. (2012)
Note that the average charge density over the simulation region is close to zero, which mean that the current sheet as a whole remains electrically neutral.
I could go on, but it is getting boring. Suffice to say that Sol's claim that the paper he linked contradicts Alfven's 'zero net current' claim form 1939, is due to his inability to understand what he is reading and quoting. Surprising absolutely nobody.
