Reading Jeremaih, it's evident that God was addressing specifically a problem with Jerusalem and his instruction is:
Jer 17:19 Thus said the LORD unto me; Go and stand in the gate of the children of the people, whereby the kings of Judah come in, and by the which they go out, and in all the gates of Jerusalem;
Jer 17:20 And say unto them, Hear ye the word of the LORD, ye kings of Judah, and all Judah, and all the inhabitants of Jerusalem, that enter in by these gates:
Jer 17:21 Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem;
Jer 17:22 Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers.
Apparently the problem WAS that the people were violating the sabbath commandment by working, carrying burdens into Jerusalem as part of working.
There is nothing in scripture that says you are prohibited from carrying anything on the sabbath. That's the type of legalistic thinking that the Pharisee's fell into.
