Yes, yes, yes, YES, to nearly all of that. Two caveats.
A Yorkshire teabag (a proper one, not a piddling little 'one-cup' one), properly brewed in a mug, is often better than some loose tea, especially when said 'loose tea' is actually a collection of roughly chopped twigs crammed into an in-pot strainer as in chi chi coffee shops who know bugger all about making tea but like to pretend they do.
It was actually Proudhon, the anarchist, who said that all proper tea was theft. Marx would probably have advocated common ownership of proper tea, or at least of the means of production, i.e. the kettle.
