Hi Markl, it seem you are ready to pay for subscription of articles if accessed privately. Given the fact there is no problem with such subscriptions as most of the publishers these days give individual price for downloading a particular article, may be $30 to $40 per article. Accordingly, when you land across any research article of your interest and want its full access, you simply have to online shop it by using your credit or debit card.

You could try adding Unpaywall ( https://unpaywall.org/) to your browser to find legal, free versions of scholarly articles
