Have you tried the alternatives lately? Impossible meat is indistinguishable from the real thing, and Quorn combined with some marmite or chicken flavoring is an excellent affordable alternative to beef and chicken.

Plant milks are pretty damn good, vegan cheese is getting close.

The others I'm a little surprised make you happier than alternatives. Plant fibers are the bomb for clothes, gas production is... Not something I associate with happiness. Mushroom leather is looking very promising as a replacement for animal leather.

Plant oils are easily as good as animal fats.

so you rather genocide billions of people than give up minor comforts ?

(hyperbole)

on a different note there are a lot of things that can and have to be changed to live sustainably but these changes have to be addressed systematically

There is almost no public transport outside cities

Having public transit to drive you around would make 99.9999% of people happier than fighting the rest in traffic.

Japan has unmanned stations in the boonies where its just 1 line that splits at stations for trains to pass. They run regular service through tiny towns this way. Elsewhere and in the event more rural areas, buses and vans fill that role.

Bicycles and mopeds can move >10x more people per lane of road and requires <1/10th the pavement for parking. You dont understand what a blight cars are on urban development and human health until you've spent time in places with effective public transit.

The meat thing is a little more subjective, IDK how far off we are from being able to reasonably get rid of all animal products, but there are certainly areas it can be decreased without negatively affecting peoples standard of living.
