The term "general welfare" does not grant any specific powers to Congress. Feel free to read this...

Congress is given the authority to make laws necessary and proper for carrying out the specific 18 things they were granted power over and nothing else. This is why they said, "for carrying into Execution the
foregoing Powers"
No, I don't jest. I genuinely know more about the Constitution than anyone to serve on the Supreme Court in the last 100 years based on their frequently blatantly unconstitutional decisions.
I posted a link to the Constitution. Cornell's opinion about the flexibility in the language of the Constitution is irrelevant. The opinions of the Supreme Court regarding flexibility are irrelevant. Only the Constitution itself matters. It means what it says and it says the federal government has absolutely zero "implied" powers.
"shoving your Constitutional experts up your ass" is an English term meant to show disrespect to someone who is owed no respect and who disrespects the U.S. Constitution.
