This video is weeks old. It also gives viewers a false impression of what's happening in Mexico, by showing only one place in only one city, the capital, as if nobody was really concerned, however, many other places in the city that are usually bustling are now deserted, and other streets just don't have as much activity as they used to, which has a negative impact on small businesses, of which there are too many (which is one of the reasons why the president encouraged people to go out and support those businesses early on, instead of enforcing a quarantine immediately: he had to choose between letting millions of informal workers starve to death and scare the entire population into panic buying, or allow those workers to keep their source of income until a full lockdown is the only option). And that's not to mention the stricter measures that some states (generally, the ones with the most cases and deaths) have been taking, and people's reactions in the rest of the country.
Of course, as in any other country, there are people that still don't take it seriously or even believe it's all a hoax, but that's plain old ignorance, not on the goverment, since they've been promoting proper preventive measures for quite a while. Also, a lot has changed since that video was uploaded. Most importantly, measures are being taken, vulnerable citizens are (supposedly) being supported financially, and a plan has been put into action since January.
Mainstream media coverage of Mexico’s leftist president Andrés Manuel López Obrador and his response to the coronavirus crisis has been terrible. While world health authorities have commended Mexico’s approach, the media — blindly parroting AMLO’s right-wing opposition — have panned it.

Despite not being in full lockdown, there's a huge campaign to persuade people to stay at home and stop all "non-essential activities".
And yes, the government's response hasn't been ideal, and I wish they acted more like this is a life-and-death situation or did something to educate ignorant people so that they'd listen, to prevent as many cases as possible when the pandemic inevitably worsens here, but it's far from being the inactive and naive government that mainstream media makes it out to be.
