I'm sure someone will say "but we need to start somewhere!". That's true, but we don't really have time for starting small. And often the alternatives are no better anyway — lots of people bought cotton bags to replace single-use plastic ones at the supermarket but that's probably worse for the environment than just continuing to use plastic (a cotton bag needs to be used hundreds of times to have a lower impact). I know that people mean well but we're all just getting stuck on trivial but attainable micro-goals while the world slowly burns around us.
Unfortunately I believe that unless our economic and political systems ("grow the economy by digging stuff from the ground and making things to sell" and "don't do anything to annoy the people you need to vote for you in N years") change neither will the climate crisis, meaningfully. And this makes me sad and terrified.
Shouldn't we tax the externalities of plastic and let the market decide whether it's worth it? In your example of using glass bottles: sure it gets rid of plastic, but what about the costs of glass? eg. increased weight or energy/water needed to clean them. As for bringing back the milkman, how is driving a truck door to door delivering exclusively milk more efficient than picking it up on your way to the grocery store?
If that were enacted tomorrow, every business would just eat the cost and raise prices.

That's what federal subsidies are for. Make it worth it to use glass, or some other material other than plastic. Subsidies are how we got cheap dairy and meat, why can't it be used for other things?

I was just spitballing, more rhetorical than anything. Milkmen used to be everywhere delivering milk in glass bottles before the plastics lobby and dairy subsidies drove them to extinction.
A good point of comparison would be plastic bags vs paper bags vs cotton bags. I think most people "feel" that plastic bags are bad and should be replaced with the alternatives, but paper bags are equal to plastic bags when you only look at climate impact, but is 43x worse than LDPE bags when factoring in "all indicators". Should we still switch to paper bags in this case?

Which is all to say that I totally agree.
Edit: there's a small glimmer of hope in the way some consumer goods are shipped from places like Amazon (in special ship-to-consumer only basic packaging). Then again those are coming from Amazon, which is ironic in its own way.
