I beg to disagree with this publication, it's their view but it doesn't matter if you are working in the office or at home, all that matters is to get the job done and be gainfully employed as a citizen of a country. In that way, you will be able to live the good life you desire and will also be able to transact financially among other people in the country which is what encourages the economy.
You sound like a politician giving vague speeches. The article actually raised some specific points so what exactly are you disagreeing about? The "net speed" is a valid metric for measuring productiveness for data entry types of jobs. The one in the office could complete the job in 8 hours while the one at home would need 2 more hours so are you saying that the extra time doesn't matter as long as the job gets done?
