Encouraging consumption in non-kosher vegan restaurants – appropriate?

To the honor of dear Rabbi Michael, peace be upon you!
A. Eating profane meat in the Torah is considered "Zevicha" – "sacrifice." A person must eat for the sake of God. Eating is not an act that is disconnected from some normative system. As part of this system, there are laws of kashrut.
on. Isaiah criticizes the sacrifices that are offered while sinners commit moral sins, and the Khuzarite criticizes the observance of Shemaic commandments without the intellectual commandments.
third. The rabbi writes that it is not certain that the entire Torah was given from Sinai. Doesn't this mean that there can be logical precedence for a custom determined from a human normative system over the versed law?
The question –
In the Rabbi's opinion, if restricting consumption from vegan restaurants that do not test their products and do not have a kosher certificate causes a national moral injustice on the level of animal abuse, is it appropriate to follow meta-halachic principles, which teach to abolish the "sacrifice" in kashrut laws in favor of the moral correction of strengthening veganism, and to instruct that kosher is not required in a vegan restaurant at all, until the national moral situation is corrected, so that the religious will take care of kosher vegan restaurants? (And it seems to me that the situation today is indeed disgraceful with regard to kosher vegan restaurants compared to those without kosher.)
Many thanks!
