Comment:
Of course this is expected and how venv works afaik:
```
$ python -m venv bad-venv
$ . bad-venv/bin/activate
(bad-venv) $ python -m sage
.../bad-venv/bin/python: No module named sage
(bad-venv) $
```

What you want can be acomplished with `--system-site-packages`:
```
$ python -m venv --system-site-packages good-venv
$ . good-venv/bin/activate
(good-venv) $ python -m sage
.../good-venv/bin/python: No module named sage.__main__; 'sage' is a package and cannot be directly executed
(good-venv) $ jupyter console --kernel=sagemath
[IPKernelApp] WARNING | debugpy_stream undefined, debugging will not be enabled

Please check if this works for you. Note that running sage like this is unsupported upstream. They really want you to build the whole kitchen sink.
