"I see it as them are knocking another nail into the coffin of Scottish culture and tradition."

I am not sure I would phrase it in this way. It is a simple fact of the world today that it is far easier, faster, and less expensive to buy weaving yarn that comes from Merino sheep from Australia or New Zealand, Washed/carded/combed in India, spun in Pakistan, dyed in Venezuela or Brazil and used in Tartan weaving mills.

Even back when England was a major wool producer, while most of the herds grazed on church land, much of the processing was done elsewhere. That is one of the ways the Low Countries got wealthy.

In Scotland the large Royal Land Grants had to raise sheep for export just to pay the taxes.

So perhaps another way of expressing it is that the current practices are the Scottish tradition.
