Lands get treated as a sacred cow of sorts that should be unharmed and those that mess with them did something very evil and may require an intervention. Yet your mana rocks though? Its fine for anyone else to mess with them. When the stark reality is that decks that use mana rocks are very dependent on such things. Stealing a Thran Dynamo may not seem like the biggest play ever, but you have unknowingly crippled the owner of that mana rock and cause them to fall behind. As the amount it produces would be like me blowing up three of your lands in terms of the mana lost.
If I choose to keep a two-land hand that has a signet and a commander's sphere and both of those rocks get blown up and I have unluckily not drawn into a single land, that is about the equivalent of "GG" and I might as well surrender due to my theoretical hamstrung state as it now has created a "feel bad" moment at the table.
Rude Awakening. Got eight lands out? Cast your Rude Awakening and entwine it. Follow it up by tapping all eight lands. Then cast your Harvest Season. Congratulations, you now have sixteen tapped lands and five floating mana.
Build as many as to your heart's content if you enjoy the deckbuilding process, I know I personally do. Also if financial issues are in your way, consider making budget decks that you can upgrade later at your whim.
