St. Francis was a mendicant. He renounced everything, all possessions and lived a life of voluntary poverty. The quote has to be taken in the context of his own calling and not everyone is called to radical poverty like St. Francis. His is one way, but somebody had to own the farm which grew the wheat which was baked into the bread which St. Francis ate.
St. Josemaria Escriva, on the other hand, teaches ordinary Christians to live lives of holiness while in a world of great plenty.
Divitiae, si affluant, nolite cor apponere, though riches may increase keep your heart detached.’ Strive to use them generously. And, if necessary, heroically. Be poor of spirit.
The bottom line is that creation and material possessions are not inherently evil. Creation is good as long as it is used appropriately and it is not a sin to own things as long as they are shared generously.
If you want to take the verse cited in your original post literally then go ahead. Sell everything, give to the poor and you will have treasure in heaven. If you are called to do so then do so. I, on the other hand, am not. I waited until I was 50 years old to buy my first new car and drove a $4000 Honda CRV without air conditioning in the heat of the deep south for ten years. What I do for the poor is my own business but know that I do give. When I look at creation I am in awe of God. I can do better but I don’t hate creation and my conscience is clean.
