While that approach might be suitable when confronting small groups or a domestic situation, it is unlikely to be successful when dealing with an unruly mob that could become violent at any moment.
Certainly correct - and that is as you know, what e.g. Riot-police is for. It is also the reason as to why demonstrations/protests need to be applied for, and maybe permitted. In order for an e.g. city and it's security members to estimate the potential of participants, respective participant groups, e.g. Antifa and e.g. Proud-Boys, in order to evaluate the potential for violence and necessary control-measures and elements that need to be kept ready. E.g. Ambulances/Paramedics, heavy anti-riot equipment, etc.
As for those Climate-Activists - e.g. those glue-bastards: what those MAGA morons and their compatriots in European countries do not understand or simply ignore - are the national laws and therefore constitutional obligation of these countries towards climate-control.
What Trump simply refused to sign (and made the USA a climate pariah) - the Biden administration signed certain UN and international climate accords.
The USA government is constitutionally committed towards protecting it's citizens health and well-being. This is what essentially "The last Generation" is using as its justification - if the government does not act according to the constitution - the people have the right to protest. The commitment of the present US administration (by Law) is e.g. to reduce CO2 emissions, at a certain % to a certain deadline. Just as e.g. Germany (way more committed towards setting reduction goals then the USA) - since every country is off target - "the population is endangered" - therefore let's glue ourselves onto the road and therefore force the government to act accordingly.
This has been Lefty&Lib strategy - especially via their radical organisations, since 40+ years - and they have become extremely good and professional at it. "If we don't get our way" according to the constitution and existing laws - we (Lefty&Libs) will "rightfully" enforce it - right down to applying violence. Just as Americans and especially MAGA radicals like Proud-boys or Q-Anon, will use violence if a state or the government would act against the law and the constitution; e.g. to take away their guns and AR-15's, or someone tells them the election has been stolen (see their own thousands of posts on USMB).
As for Laws:
Laws can be anytime introduced and amended in the USA and any other fake-democracy - regardless of political opposition or the seat distribution in the Senate, if e.g. $$ and favors get involved in the GOP and or for the Dems. To state that presently the Senate is controlled by the Dems, and therefore laws can't be enacted is pure nonsense - since in fake democracies the enactment or amendment of laws is daily routine business. This is exactly were this endless corruption and manipulation comes in - since fake-democracies are entirely run by politicians and elitists, and NOT by the people aka plebiscites.
Classic example - the passing of the climate control bill in the US Senate - (Kigali Amendment) September 2022.
Vote count in favor 69 - against 27, keep in mind the seat count in the Senate is GOP 49/Dems48/Indep3
So why did the GOP support a climate-control bill in the Senate? - therefore factually supporting Climate activists !!
Because they were lobbied by the appliances industry - who promised themselves huge profits via the introduction of new refrigerators and air-conditioners. (Big US and global business) and one can be sure that due to the GOP supporting a Dem Bill - they treated other favors or future favors for it. It's daily political business and that is how every fake-democracy (exception only being Switzerland) is run.
Thanks & have a great weekend too
