“if you cannot take the heat, get out of the kitchen.”
That is not an option.
Torah was given to an entire nation, not to a small pious sect. Any Takana that the majority of the full nation can not live up to is not binding.
In any serious profession, the bar will be set such that most of us can not meet it. The Torah standard can not be that, as all our children are bound by it.
For example, most guys can not sit and learn full time on an ongoing basis. If that is set as the standard, most will either deceive themselves that they are actually learning full time or give up and go OTD.
