My friend I gathered many sutta for your benefit! 
“Those who dwell deep in the forest,Peaceful, leading the holy life,Eating but a single meal a day:
Why is their complexion so serene?”

“Good, good, Kassapa! You are practising for the welfare and happiness of the multitude, out of compassion for the world, for the good, welfare, and happiness of devas and humans. Therefore, Kassapa, wear worn-out hempen rag-robes, walk for alms, and dwell in the forest.”

Maha Kassapa was trying to maintain the long tradition from Past Buddhas. And Buddha compared him as himself in accomplishments. So Buddha alike.
Inspiring are the forests in which worldlings find no pleasure. There the passionless will rejoice, for they seek no sensual pleasures.

The following one cleary shows that following Buddha’s example is living in the forest.
Master Gotama, those gentlemen who have gone forth from the lay life to homelessness out of faith in Master Gotama have Master Gotama to lead the way, help them out, and give them encouragement. And those people follow Master Gotama’s example.”
“That’s so true, brahmin! Everything you say is true, brahmin!”
“But Master Gotama, remote lodgings in the wilderness and the forest are challenging. It’s hard to maintain seclusion and hard to find joy in it. Staying alone, the forests seem to rob the mind of a mendicant who isn’t immersed in samādhi.”
“ I considered thus: ‘Whenever recluses or brahmins devoid of wisdom, drivellers, resort to remote jungle-thicket resting places in the forest, then owing to the defect of their being devoid of wisdom and drivellers these good recluses and brahmins evoke unwholesome fear and dread. But I do not resort to remote jungle-thicket resting places in the forest devoid of wisdom, a driveller. I am possessed of wisdom. I resort to remote jungle-thicket resting places in the forest as one of the noble ones possessed of wisdom.’ Seeing in myself this possession of wisdom, I found great solace in dwelling in the forest.

As long as the mendicants take care to live in wilderness lodgings, they can expect growth, not decline.

Bhikkhu Nanamoli recounts Sutta Vibhanga to illustrate this episode in ‘The Life of the Buddha’.
“…Lord, what was the reason why the holy life did not last long in the time of the Blessed Ones Vipassi, Sikhi and Vessabhu?”
Those Blessed Ones habitually read their disciples’ minds and advised them accordingly. Once in a certain awe-inspiring jungle thicket the Blessed One Vessabhu, accomplished and fully enlightened, read the minds of the Sangha of Bhikkhus a thousand strong, and this was how he advised and instructed them: ‘Think thus; do no think thus. Give attention thus; do not give attention thus. Abandon this; enter upon and abide in this.’ Then by following his instructions their hearts were freed from taints through not clinging. And that jungle thicket was one so awe inspiring that normally it would make a man’s hair stand on end if he were not free from lust. That was the reason why those Blessed Ones’ holy life did not last long.”
And the last one is what I meant with Original Buddhism. But like you saw Buddha said
As long as the mendicants take care to live in wilderness lodgings, they can expect growth, not decline.
That’s the reason why there is still Buddhism. 



May you dwell in the forest one day and full accomplish as Maha Kassapa. 
It’s still Tradition that the period of rains retreat was the only moment Buddha didn’t allow living in the forest. But that rule came after because the householders complained. The same is for full moons. Before Monks just stayed silent then Buddha changed the tradition because householders complained.
The point of Buddha was not against the points asked but thinking that in the future we will have city monks etc. But real Buddhas followers is like Maha Kassapa.
