Many of us see Messiah Yeshua as making quite a number of His own fences/halakah and specifically instructing His students to obey the teachings of the P'rushim, aka halakah, just not with the kavanah/heart attitude some of them had.

From my perspective:
Some of the Perushim were also judges.
Deut 17:12 The man who acts presumptuously by not listening to the priest who stands there to serve the LORD your God, nor to the judge, that man shall die; thus you shall purge the evil from Israel.
Matthew 32:1 Then Jesus spoke to the crowds and to His disciples, 2 saying: “The scribes and the Pharisees have seated themselves in the chair of Moses; 3 therefore all that they tell you, do and observe, but do not do according to their deeds; for they say
things and do not do
them.
It was the law that the people had to obey the Priest and the judge. They sat on Moses seat, which would be the position of the judge, so according to the law, they were to be obeyed.
Acts 23:3 Then Paul said to him, “God is going to strike you, you whitewashed wall! Do you sit to try me according to the Law, and in violation of the Law order me to be struck?” 4 But the bystanders said, “Do you revile God’s high priest?” 5 And Paul said, “I was not aware, brethren, that he was high priest; for it is written, ‘YOU SHALL NOT SPEAK EVIL OF A RULER OF YOUR PEOPLE.’”
So, if there is a valid court of judges and a valid High Priest, according to the Law of Moses, these are to be obeyed.
Jesus did come against the Perushim concerning that additions to the law and taking away from the law.
Deut 4:2 You shall not add to the word which I am commanding you, nor take away from it, that you may keep the commandments of the LORD your God which I command you.
Halachah is not a bad thing, unless that halachah adds to or takes away from the commandments of the Lord. Then, the adding to or taking away is actually a violation of the law. When the Temple, the priesthood and the Sanhedrin were in place, it was a requirement to obey them.
I do not believe Yeshua was adding His own Halachah, but was actually explaining the law.
I do believe the Rabbis overstepped their mandate. Starting with Yavneh.
