If you tax land with higher taxes for lower density, then, yes, you’ll radically increase food costs.

This would encourage property density in high value locations like inner cities but wouldn't enforce it.
In terms of farmland it would just mean that farmers rent the land from the government rather than, say, blackrock or bill gates (two of the biggest owners of farmland right now).
This would not affect food prices by much it would just mean that when you buy food from those farms, instead of ~15% of the price flowing into bill gates' pocket it would flow into government coffers. Bad luck Bill Gates. Bad luck Blackrock.
I wasn’t responding to an LVT suggestion, but a suggestion of taxes that would be based on density of use and go up for lower density. I quoted the suggestion in my response. LVT is a whole different thing.
