There are no satisfactory "answers" on how to make progress. Because the only actual answers are painfully and slowly. By educating and convincing others. So it always boils down to impatient revolutionaries trying to do it by force. Fundamentally failing, and setting everyone back again and again.

Even Marx phrased it as "evolution" not revolution. And like you said it starts from the bottom up. Revolution has only made the educated and ignorant alike fearfully clutch to capitalism. Because the ideology of the revolutionaries is a lateral move. That wouldn't actually make things better. And would see a lot of people needlessly killed.

The one, possibly best thing we could do. Is for interested, individuals to start pooling their money to buy land. Then build high density, communal housing and sustainable communities. Dedicated towards proving socialist/small c communist principles. Ideally with people able to help replicate such communities. Where there will be no Lords of any sort. And rent will be the cost of what is needed to maintain housing. Not someone's luxury. The funds to get started would be the biggest hurdle. But once people see there's nothing to actually fear. And for younger generations, lots to gain. You'd see a lot of people warm up to the idea.
