> Winston Churchill said that democracy is the worst form of Government except for all those other forms that have been tried from time to time.
Sure but he had a good reason to conflate all forms of democracy as if there were no difference between them or ways to give more power to the people in, say, UK's form of democracy. Replacing first-past-the-post voting for example wouldn't require abandoning the entire system of government.
> The same for capitalism.
Sure but again there are important differences between laissez faire capitalism and a social market economy and yet this is used to justify reforming the latter into closer and closer approximations of the former. This also ignores that while the economy at large is clearly some form of "capitalism", communities otherwise operate on more non-capitalist patterns of behavior (e.g. buying rounds at the bar among friends, borrowing tools to your neighbors, BYOBs/potlucks).
Even interactions involving currency (remember markets and currency alone don't define capitalism) don't have to be transactional or profit optimized or be defined in terms of ownership and servitude. Of course things like the gig economy, consumerism and "hustle culture" are built around "capitalism"-ifying those non-capitalist interactions by reframing them as transactional or business opportunities - the most blatant example probably being the widely ridiculed genre of blog post a la "what breaking up with my partner taught me about being a hiring manager".
