Exactly. You don’t get very far at all before perfectly natural divisions of time can’t divide evenly by 10. You can’t “fix” it, like you can with mass or length, unless you demand people give up on centering time around astronomical events. The second is an SI unit. Science can be done in seconds. Anything else just shifts the awkwardness of orbital mechanics elsewhere, while pissing everyone off.
My main point is that you’ve done nothing but kick the can down the road a little bit, so people decided it wasn’t worth the trouble. It’s annoying that there 60 seconds in a minute, 1800 in an hour, ~86k in a day, fair enough. Let’s say you make a new metric second that has 100k in a day. You make certain things easier, but how are you keeping time on anything like a larger scale?
You can probably come up with something fairly usable with ten-day weeks, but what about years? This is is where it breaks down. A year is based on astronomical events, but different ones than a day, both are deeply ingrained into the routines of life. It is 365 and a a quarter (-ish) days in a year. We’re stuck with that, unless you just want a number that has no useful context for humans after a few years. Throw in that you also have leap seconds to add every so often, and in the end it’s still going to be a mess of decimal units that go unused, and customary units that will not be given up, but with all the drama of making a change.
There is no single bandaid to pull off, so it’s not the obvious improvement that other weights and measures are, because time is more fundamentally rooted in our experience as animals than what we label a given amount of stuff.
Decimal time works perfectly. For years, as you say, you are stuck by how long a year is. All you can do here is better divide the months. 13 x 28 days is my preference.

Can you explain this argument to me.
The second is currently a fixed length, there’s a fixed amount in the day and we don’t adjust it now.
So how would it be any different if we changed the amounts?
